Hi all, i just recently bought a picco .26 max for my t-maxx. so far i broke it in, and runs ok, but now when i gun it completely it quickly builds up rpms and then stalls like if i let go of the throttle... why is it doing this... motor is still runing pretty rich, decent amount of smoke comes out of the exhaust. the idle is perfect, and the motor is not over heating, yet stalls at high speed... do i need to lean out the low speed and richen the high speed?? sometimes it stalls when i floor it from a stop/idle... been a while since i mess with rc engines anf forgot what i was doing... please help!!!

thanks, tony
