i have a .15 cv-rx with pull start and bump start. the motor will fire up and run for anywher from 10 seconds to one minute and then die. it has plenty of fuel flow,the glow plug is new and appears to heat up fine. when running, it doesn't have enough time to get hot. the rotary carb settings are at factory settings. ***the motor was being used on a t-maxx before I acquired it, it ran fine.

Your engine's not running well because it's most likely not adjusted correctly. You'll need to check how the carburetor's set up. "Factory" settings are only starting points. You have to get the carburetor adjusted for your setup. You'll have to get the high-speed needle properly-adjusted and then get the idle mixture properly-adjusted.

hi,it could be rich or lean ...turn the main needle fully in and then turn out 1 and a half out close to 2 ,try that
