New T-Maxx 3.3 running problems
I was on my 5th tank of gas following the break-in procedure to a T. But all the sudden it will stall when I try and go to full throttle. It will run at slow speed, but every time I gun it, it will cut out. I followed the book and tried to richen the high speed mixture.
Any suggestions?
Is there a magic amount of times to back out the high speed needle when it’s turned all the way in? How about for the low speed and idle screw as well. I am pretty sure that I will adjust the idle to where the wheels stop spinning.
Any help?

RE: New T-Maxx 3.3 running problems
the factory settings are right in the manual.....go back to them and try again.....it may have been too rich as well.

RE: New T-Maxx 3.3 running problems
if you turn the hsn all the way clockwise until it stops and then back 4 full turns it will be at factory settings.. the the lsp make sure it is flush with the outer casing. then that will be at factory settings.. also after the 5th tank or even at the 5th tank there is a real good chance that the glow plug is bad.. even if it glows a little it still could be bad..
i would change that because it is due anyway,, reset your needles and then adjust.. you should be set then. jake

It will run great at slow speed, but as soon as I hit the gas to go to full throttle, stall city.
Could this be an overheat issue?
Also, I can’t seem to adjust the idle screw enough to get the wheels to stop spinning. It seems to be idling very high?
Also, I can’t find anywhere in the manual that shows how to remove the glow plug wire. I need to remove the glow plug wire so I can pull the plug and put a couple drops of after run oil down the head.
Thanks again,
JAM

RE: New T-Maxx 3.3 running problems
Come on guys, I'm not asking for all the ansewrs, just the ones I can't find in the manual or the videos. I got the glow plug wire out.
Anyone think I may be having an overheating issue with the motor that would cause it to stall at high speeds? It will run great at slow speed, but as soon as I hit the gas to go to full throttle, stall city.
What about it idling high with less than a 1mm gap in the carb??? How else can I slow it down, should I adjust the throttle trim on the transmitter, it's dead center now?
I got the glow plug wire out with some needle nose pliers and plan to replace the glow plug tomorrow.
Thanks,
JAM

RE: New T-Maxx 3.3 running problems
Settle down dude. It's been an hour since your last post. Maybe the people that are on at the moment do not have the exact answer and those that due have something else better to do.
I'm still waiting for my new T-Maxxfirst ever nitro vehicleand I do know one thing: an abnormal idle that is abnormal is due to a vacuum (air) leak.
Take the advice of others, replace the glow plug and do what they say. With toys such as these, even with vehicles (in a sense this is what they are) there is not always going to be someone to take you by the hand at each step or issue. Most of the time it is trial and error and putzing around with it to figure things out. That is when you will learn.

RE: New T-Maxx 3.3 running problems
Jambf, I started breaking in my new 3.3 on my old revo and have a simlar problem with the idle, but doesnt stall at higher throttle. Mine runs too high of a idle and the temps climb. I had to back my idle screw down to like .3mm gap to get it to idle down and it still idles a bit high even with my my Lsn and Hsn as rich as I can get them. I have owned alot of 3.3's and this is a very good indication of a leak somewhere. It is not normal. I started looking for my leak and found a couple on my carb Hsn and a allen bolt on the carb, probably the throat is leaking too. I have a different exhaust set up but I checked it all out and everything else seems sealed tight. On yours it sounds like you got a leak too somewere. I could be wrong, but I would start leak testing and looking for one asap before you run it or you will damage the motor even more. Mine isnt bad so no big deal. Just got to put my new carb on and fixed. Here is a good way to do a leak test. Since its new just look over the whole thing exhaust, header, backplate, fuel lines, tank, Hsn, Lsn, carb, front bearing seal. If you didnt get it dirty and never spilled any fuel, you should be able to see a leak pretty easy. To make sure on the tank just take it out and block off both the pressure line and fuel line going out and put it under water and look for bubbles. For the throat of the carb you will not see fuel leaking so you can test that a few different ways, one way is to take the airfilter off and pull the fuel line off the tank and blow into the fuel line going to the carb while holding your finger over the carb inlet and spray windex around the throat of the carb. If you see bubbles coming out from around the throat of the carb as you blow through the fuel line, you have a leak. Another way is just run the motor and spray wd-40 around the throat of the carb and if the idle changes you got a leak. Most of the leaks are from the carb with new trucks. I rarely see leaks in other areas with brand new trucks but check everything to be sure. One more thing, I would get a temp gauge if you got the money. Its worth it if your new, it may save you a motor. It even helps me diagnosing problems after I have been in this hobby for years. My temps climb at idle, and I knew I had a problem with a very rich setting like that. Plus, I know to shut it off if they get too high fast. A leak can sky rocket temps fast and toast a motor, the temp gauge can tell you a problem exist very easily.

RE: New T-Maxx 3.3 running problems
If your carb is leaking, I can give you some advice on fixing it. But since its a brand new truck you might want to call traxxas and they will probably give you a big run down on the phone on things to check, in the end they should send you a fix in the mail if you need one. Traxxas does not recommend sealing your motors and they will probably not warrenty them if you do it so be careful if you take that route. I ended up just getting a new carb through traxxas since mine was a new motor and under warrenty. I will admit I have had excellent results with sealing my motors after they get older, but I dont send those in to traxxas and usually wait till they get passed 3 gallons or so out of their warrenty so to speak period. Just make sure if you do decide to seal the motor, do it correctly or you can do more damage than good.

Jake, thanks for your help and not saying I should first read the manual and watch the DVD because I did and this started on its own prior to me touching anything. I was just beginning the 5th tank.
It will run great at slow speed, but as soon as I hit the gas to go to full throttle, stall city.
Could this be an overheat issue?
Also, I can’t seem to adjust the idle screw enough to get the wheels to stop spinning. It seems to be idling very high?
Also, I can’t find anywhere in the manual that shows how to remove the glow plug wire. I need to remove the glow plug wire so I can pull the plug and put a couple drops of after run oil down the head.
Thanks again,
JAM

you might want to read it again slowly....all of your questions are answered in the manual.

Where in the manual does it say my motor may have an air leak causing it to idle too high? I read the manual about the idle setting and trying to richen the motor to slow down the idle...that doesn’t work.
AGAIN...if you don’t want to answer with some solutions or help, that is fine, just don’t read my post and we won’t waste each others time. I thought this forum was a way to teach, learn and communicate with people that enjoyed the same hobbies as you.
I have only been on the Traxxas forum for one post and already 2 negative comments. Does grumpy old men come with ownership of a Traxxas?
BTW, I’m 42 and so I’m not really calling anyone old…accept for me.
MSpeed, thanks for the advice. I will begin the check for air leaks and invest in the temp gauge.
Systemlord, thanks, that seems like a simple test to do.

Why did you even bother to respond? I sure didn’t need that advice! I also said thanks to everyone that had responded and didn’t think I was getting impatient. For your info, I am changing the plug and just discovered from another REVO post that it could be an air leak (which stinks on a new Truck)
This is a hobby that my son and I recently got involved in; we are having a ton of fun and sharing some great quality time together. We have two different trucks and have learned a ton from another forum on here.
I’m not asking you to take me by the hand, but I will ask you this, if you see a future post from me, do us both a favor and pay no attention to it.

RE: New T-Maxx 3.3 running problems
first,,, change the glow plug,, then reset the needles back to factory like i mentioned earlier.. now it should start real easy.. then as fast as you can get the truck to go drive it until you get the engine warmed up. did you try the pinch test? you know where you pinch the fuel line and see how long it takes to shut of..
it should run about 3 seconds then speed up,,then shut down.. if it doesnt then try adjust ,[lean] your low speed needle.. trust me buddy,, i am about your age too and am brand new to this hobby.. i bought the revo3.3 and 3 weeks later bought the tmaxx 3.3.. for first timers this can be a crazy hobby..
on my revo right out of the box i could not get it started.. i tired a number of things.. i also had a couple wise guys give me answers that were rude too:}:} there are a few on here but 99% of the guys will and can help you. on my revo it turned out to be a bad ezstart motor right out of the box.. traxxas sent me a new one out right away for free.
then after running my 5 th tank on my tmaxx i let the truck sit for 5 hours.. then when i tried to start it i could not get it running.. i had fuel spitting out of the exhaust.. i pulled my glow plug and tested it using a glow ignitor. it looked good to me but i took someones advise and changed it anyway.. the truck started right up.. then it would want to roll with out me touching the throttle.. too muc idle.
so i reset all my needles,,hsn and lsn/// then i ran the truck as fast as i could for a couple laps.. then when i gave it the pinch test it took too long to cut of so i leaned the lsn a couple notches.. i now have it running pretty good but i know it still needs some tuning.. we have had a ton of rain here lately so i am not able to run it.
but dont give up or get too frustrated.. these can be a pain but once running right you know how much fun they can be. did you try to call traxxas? i tell ya,, they are great.. they answer the phone RIGHT AWAY and you can actually undersand the words that are coming from their mouths:}:}
i dont dont think you would have an air leak.. but what do i know!! i would bet it is just a matter of tuning.. so,,get a new glow plug,, try resetting the needles again!! and i am not sure how to get the idle screw back to factory but try traxxas,,,they will tell you..
hope you get it buddy... jake

Normally, if the engine goes at slow speed but cuts out as you go faster, the HSN is too lean. If you keep on burning glow plugs, or the piston has a bluish tinge on it when you open the engine, that's a sure sign that its running way lean.
If the HSN is way rich then the motor will also cut out when you open up the throttle. An easy way to check this would be to remove the glow plug as soon as the engine cuts out. If the glow plug is wet, then that's a sign that the settings are too rich. Also, if the glow plug is black and fouled up, the engine is too rich.
I would say those 2 scenarios would be your starting point.
Things like air leaks on the carbs etc. would be your secondary line of investigation and can be a real pain in the butt to find sometimes.
If you put a new glow plug in and return the needles to their factory setting, and the motor is still untunable, then my assumption would be that the problem does not lie with the glow plug or the LSN/HSN, and that its time to look for air leaks.
Failing all that, take your truck to the local race track (if there is one) and see if there's an experienced person there who is willing to help you. I have been helped before in 5 mins by an experienced person on a problem that would have taken me days to fix.
The Traxxas manuals are some of the better R/C literature I've seen but sometimes you are so confused or far off the mark that the manual becomes irrelevant.
Good luck!!!

RE: New T-Maxx 3.3 running problems
no problem, I think you will find a leak somewhere assuming your needles are set rich. First time you do leak testing/checking its a pain, but after you learn, you will be so much better off down the road. Lot of people dont learn how to check for leaks much less look for them and end up with tunning issue through out most of the life of their motors. Its is a very important skill to learn. Makes your experience with nitros much less frustrating later on.

RE: New T-Maxx 3.3 running problems
JAMBF750 I forgot to mention that on my fourth tank of nitro when my Sirio was new, it began to rise in idle quite at bit. This happens because the sleeve and piston are starting to glide much smoother than when they were so tight and new. When it started iding higher I knew my engine was closer to being broken-in, if the idle screw is not lowering your idle then you defently have an air leak. Another thing that will make your idle high is being to lean, when I'm warming up my engine and the idles to high I richen it up on the low side and maybe a little on the high side and then my idle comes down a bit. What fuel you using?

RE: New T-Maxx 3.3 running problems
ORIGINAL: JAMBF750
I was on my 5th tank of gas following the break-in procedure to a T. But all the sudden it will stall when I try and go to full throttle. It will run at slow speed, but every time I gun it, it will cut out. I followed the book and tried to richen the high speed mixture.
Any suggestions?
Is there a magic amount of times to back out the high speed needle when it’s turned all the way in? How about for the low speed and idle screw as well. I am pretty sure that I will adjust the idle to where the wheels stop spinning.
Any help?

Where in the manual does it say my motor may have an air leak causing it to idle too high? I read the manual about the idle setting and trying to richen the motor to slow down the idle...that doesn’t work.
AGAIN...if you don’t want to answer with some solutions or help, that is fine, just don’t read my post and we won’t waste each others time. I thought this forum was a way to teach, learn and communicate with people that enjoyed the same hobbies as you.
I have only been on the Traxxas forum for one post and already 2 negative comments. Does grumpy old men come with ownership of a Traxxas?
BTW, I’m 42 and so I’m not really calling anyone old…accept for me.
MSpeed, thanks for the advice. I will begin the check for air leaks and invest in the temp gauge.
Systemlord, thanks, that seems like a simple test to do.

you might want to read it again slowly....all of your questions are answered in the manual.

RE: New T-Maxx 3.3 running problems
Thanks to everyone that had a positive response and some good suggestions. I have tried most and now working with Traxxas customer support and they are determined to get it fixed...i have talked to 3 diferent techs and we did a gas leak test, removed the HSN, and turned more in and out screws on the carb than you can shake a stick at. They are awesome to work with and together (also with your help), we will get it fixed.
Thanks Again,

RE: New T-Maxx 3.3 running problems
I too will be interested to find out what was done to resolve the problem as well; because like systemlord mentioned it would serve as a good post for anyone else that might encounter the same problem(s)

RE: New T-Maxx 3.3 running problems
I will be calling Traxxas later this afternoon. Just getting back from a fishing trip in the Gulf of Mexico...we stayed on the boat for 3 days...what an experience.
Thanks all, I will post up later, they want to hear the truck running over the phone...this should be fun.
Later,
JAM

RE: New T-Maxx 3.3 running problems
OK, the truck is going back to Traxxas. We (Traxxas technical support and me) worked a couple hours today trying different things to get it running at full throttle. Trust me guys, with the exception of looking for a major engine leak (perhaps coming from the carb), we did a bunch of different test and nothing worked. They all agreed that I should send it back.
I’m certain they will discover something called out in one (or more) of the above threads, but I don’t think I should be checking for major leaks on a NEW vehicle…… period. If it’s bad, they should fix it and pay the freight to and from. Of course, I am willing to pay it now and see what they find out.
You want to hear the funny thing; I have a Redcat Volcano SV Pro that runs awesome, but I (actually my son) have had some bad luck breaking little things. Like the front left dogbone keeps falling out when my son hits a good size jump. Just like Traxxas, there are fixes for almost any reoccurring problems (inserting a very small section of fuel tubing prior to inserting the dogbone); it just takes some time, patience and some good know how (or a good chat forum) to really enjoy this hobby. Maybe I should put the Infinity motor on the T-Maxx mechanical frame and I would have an awesome truck.
I’ll keep you posted on the outcome.
