Question

I just finished breaking in my rc car motor. Runs fine, but when I give it full throttle it cuts out.

Answer 1

When you open the throtle it gives a blast of cold air and shuts down the engine. Try openning the throtle slower and smoother. Once the RPM is up you should be able to floor it. You can try increasing the length the air intake tube to warm the intake air. Or change the couling so warm air from the engine is diverted toward the carborator intake.    

Answer 2

you may need to adjust your carb.
