i just got my hpi rs4 3 today and i was going to break in the engine
i started in full tank with no movement just idle the engine
in the second tank i drove the car in 8 shape lane driving in half throttle Ease on and off the throttle (alternately ).
and of course taking break between the tanks to let the engine to cool of.
in the third tank the engine start to not working in a stable rpm and every time i hit the gas (i meen hit 1\2 throttle) the car engine stooped working and sound like it is start to move spasmodically and stops.
i think it is getting to rich so the engine is flooded , but us far as i know i don't spouse to tune the engine before i finish to break it in, in my other car (mantis) i did not tune the car before i finished to break it in.
please help me with that if you know anything about it!!
