im building a blaster right now and its got an lrd pipe, reads, porting, and an old 34mm round slide mikuni that came from a snowmobile. my problem has to be something to do with jetting since i don't have a clue were to start. what it does is it will run as i kick it and die once i stop kicking it, in the idle position. it smokes really bad as i do this so it must be really rich. it wont do anything at all in any other position but idle. i changed the 310 main jet for a 240 main and it still does nothing when i give it throttle. the pilot jet is a 55, could the pilot jet be the problem? when i hold it full throttle and kick it it doesn't fire, but it doesn't smoke either, but i doubt its lean becasue it did the same with a 310 main. something must be wrong other than jetting? or maybe im just way to rich all around? im normally good at jetting 2 strokes and i know what im doing but iv never started with absolutely no starting point before so i need to know what its going to take to get m in the ballpark so i can start fine tunning.
o yea, and i cleaned the carb extensively. its as clean as a brand new carb.
