engine dies
 

Hi, i just finished breaking in engine. after couple pull of FULL throttle, my engine dies. (happened twice today during two tanks)

so i tried to restart the engine, BUT this time, whenever i pull the pullstart, the engine was VERY rough. i tried couple more times and gave up cuz i didn't want to mess up my engine. I cleaned the engine with WD-40. i couldn't go to my LHS to buy after run oil, but i'll buy one soon.

what caused my problems?? I'm a newbie at nitro, so please help me. Thank you very much.

I have HPI RS4 3 SS with .12SS engine.

take it to your hobby shop and ask them to tune your motor then tell you how to keep it running and all that other good stuff..
