Revo keeps stalling!!
Hey everyone,
I got a quick little question about my Revo 3.3 Last few days I have been having some problems with my Revo 3.3. Just this afternoon I was actually using it, nice and sunny and around 64F out side. Great wheather to run in. Anyways, it seems after a minute or so of using when ever you come to a stop or even let go of the throttle for a little bit it shuts right off! It does this when taking off a bit. But i'm like 80% sure that it is not any of the gauges or to lean or anything like that. Revo expert at the hobby store tuned it about a week ago, I made no adjustments since. I've changed the glow plug quite a bit within the week as well. 2-3 times. Seems like there going through quickly. Anyways, after it stalls it has a really hard time starting to, sometimes it won't kick in until you let it sit a bit. My EZ start controller and glowplug heater are both charged very full.
So i'm wondering if this has happened to anyone else before? Do I need another new glow plug!? The one I got is like a day old. It starts, but seems to be stalling. The engine is warm enough, I just don't get it. It's all tuned great.
Anyone have any suggestions to get it running back to normal?
Thank-you.

RE: Revo keeps stalling!!
Dito, need to tune everyday to the weather conditions, if its doing it at idle its a combination of the low speed jet and Idle screw, and remeber always make very small adjustments (1/4 turns) on a WARMED up engine.. Hope this helps

RE: Revo keeps stalling!!
Well it seems tuned right, it's just stalling a lot. I don't know if it's to rich or lean or what.
How should I tune it? The temperature now is like 72F, when tuned it was say, 60?

RE: Revo keeps stalling!!
it may "seem" tuned right to you
but it is not
the stalling thing is an indication of a bad tune
we cannot say if it's lean, rich or what
but that does not matter anyway
reset the needles to factory and tune the engine
tuning is a huge part of owning and running a nitro rc
to learn how read your manual and watch the dvd that came with your truck
if you don't have that
go here

it's not hard
it just takes practice
good luck

Thanks for the reply. And yes I do have the manual and DVD and all that information about tuning and what not, although i'm not convinced that is the problem. I just brought it out litereally 10 minutes ago, and same thing, keeps stalling. It seemed a bit lean so I thought it might be from not enough fuel going through, so I richened it up quite a bit, and it still stalls. Sometimes it even stalls on a high RPM, that should not happen. I'm quite convinced that it is a bad glow plug. When first starting when I take the glow plug heater off, it will shut off imediately if I do not keep it revved. I'm quite possitive that it is the glow plug, if so, what is causing them to burn out so quickly? I've went through 2 bran new ones and I barely even used them! I'm running on the McCoy MC-8. Medium - High heat glow plugs. The go by pretty quick, is this normal? Is it possible them to become junk after short usages?
That is what i'm stuck on at the moment.

Have you turned the motor over by hand? how is the compression?
Is there oil build up by the fly wheel around the front bearing? could be an air leak?

RE: Revo keeps stalling!!
Not to sound like a know it all, but I'm pretty good with those nasty little buggers(nitros in general), but I have in my time run into the exact same experience as Jeff & bono(with the Traxxas mills). You can tune and check for leaks for days and it'll run exactly the same! I'm not bustin' on Traxxas but I've heard this same story sooooo many times. Seems some were good engines and some weren't. Even a good one is very sensitve to proper tuning, moreso than most! I gave up and got an OS18TM. Been ear to ear grinnin' ever since! I here there's a 21 TM now[>:]!

Orrrrrrrrrrrrrrr before you go crazy with the tuning stuff you could just check the clutch spring to make sure its not broken or missing all together. If its the spring the car wont idle and is hard to start, but will work under throttle. I would start there. One way to check without taking things apart is to see if the car tries to roll when you put the Ez Start on. If it does your spring is no good.

And like any good forum user will , post back when you get it figured out to help the rest of the community.

RE: Revo keeps stalling!!
I would richen it up on the low end and replace the Glow plug. Sometimes the glow plug is bad. They do just go bad some times.

RE: Revo keeps stalling!!
Check if you engine has compression by trying to turn the flywheel with you hand, if it gets very difficult at some point then the engine's good, but if it turns over very easy then you going to need to replace your piston/sleeve.

Or do the Traxxas exchange.

You'd save quite a bit of money changing it yourself, A new piston/sleeve for the 3.3 is $60-$70. The traxxas exchange is about $120 to $130 I beleive.
