Ok... Here's the deal... I've always wanted a nitro RC car, but couldn't afford one. The other day, a friend of mine gives me one because he's leaving town with the clothes on his back and can't take any of his stuff with him. I don't know anything about nitro cars, but as of today, I can totally tell that this is hobby is going to suck every last dime outta my pocket!

I don't know the model of the car, but I've determined that it's some kind of a Team Associated 2wd buggy. The engine is not stock--it's an OS CZ-Max (that's all I can decipher from the side of the motor) with a BK carb on it. Here's the problem(s):

#1) I can sometimes get the motor to fire, but it's rare. Sometimes, it'll just spin and spin and dump fuel into it, eventually flooding it. When it does run, it runs pretty good. I finally was able to get it started this afternoon, and drove it for the first time down a little side street next to my house (with brand new asphault!)... It was truly AWESOME. I ran it up and down a few times, and then the engine stalls. Plenty of fuel in the tank.. it just dies. Tried everything, but I can't get it started again. I'm sure when I try it tomorrow it'll fire right up again, because in the last few days, I have fired it up about 15 times, but after I either stall it while trying to tune the carb, or pinch the fuel line to shut it off, I can't get it started again for a while... I tweek everything 3 or 4 times, and then it'll start again...

#2) Don't have a starter box, but I do have the starter motor itself and a rubber wheel (that since it's not mounted, keeps rubbing against the chassis when I try to start the engine, and is getting really small). Does anyone have some plans or pictures of a starter box that I can get an idea from so I can build one? The other thing is, how far up should the flywheel be from the bottom of the chassis when you're looking at it from undernieth? 1/16"? 1/8"? Less? Flush with the bottom?

Here's what I have done tuning-wise to the engine:

The low-speed mixture is set about 1/16th of an inch out (about 2 turns), and the high-speed mixture is set at three turns. Idle stop is set at 1/16th of an inch. The motor has been used before and was broken it before I got it.

Any information leading up to the regular starting of my engine would be most needed, helpful, and greatly appreciated.

Thank you all, and thank god for this website.

PS: Anyone have this motor and have a PDF file for it? I know it's old...

Problems solved... I went out today and spent $79.99 on a Team Magic X5 starter box, and another $18 on a nice glow plug ignitor. Now that I've set the box to my car, the engine fires every time now. I returned the Hobbico Torqmaster 90 hand starter--it just wasn't going to work. Threw away my friend's home-made glow plug starter (made with alligator clips! <Ugh!&gt. Now all I need to do is pull all the components off the car to clean the combination rubber and nitro grime off all the parts and chassis, and replace the 65 tooth drive gear, and the clutch assembly... I hit a curb last night, and it jolted the motor forward enough to barely make contact with the drive gear-shaved all the teeth off, and the carburetor needs to be worked on because it revved up really high, and I vibrated the drive gear, clutch disc and housing off the car... Those seems to be the only problems now--I bent the front end back into place, so it works again...

If it's not one thing, it's another...
