Hey i'm a newbie to nitro's and I have a Cen TR4 Awesome car launched it off the curb by accident twice and nothing has happened. But I have ran 10 or so tanks of fuel in it and sometimes wen i first start it it starts for like 3 seconds then stalls and sometimes it stalls when i'm runnin it like i'll let it idle for like 5 seconds and it stalls. Why does it do that. O ya o havn't adjusted the idle speed or high speed or low speed needles. What could be the problem?

Try adjust the low-speed and high-speed. Also adjust the idle screw on the carb. Don't make it to tight. That screw controll your idle speed. After awhile it will come loss just enough to make your car shut off at idle.

I had a similar problem with my CEN TR4.

Problem was a leaky exhaust. Because there was no backpressure, the engine couldn't get any fuel. Check all the seals on your exhaust, throwing another tie wrap on where necessary
