"things are breaking"?....like what?...drill starts dont always solve starting problems...if anything they can make them worse...if you keep trying to start a unproperly tuned rc with either a drill start or bump box you can knock the pinch out quick fast and in a hurry (trust me on this...I know from personal experience)

what kinda rc and what engine?....not always are the engines set were they will start new (trust me on this also...and yeah personal experience)....running a nitro is a learning curve....and beleive you me I still havent mastered it..

not sure you have done this...but screw your high speed needle all the way in (gently, dont tighten it when it bottoms out)...then turn it back out 2 1/2 turns....then screw in your low speed needle all the way (once again dont tighten it)....then back it out approx 2 3/4 turns....

once you got that done turn on the transmitter and the reciever....set your throttle trim to the center....then pull off the air filter and look down the throat of the carb...adjust it to 1mm opening....once adjusted apply brakes...the 1mm adjustment shouldt change....

this should get you running...then tune from there...
