ok now im starting to get frustrated.im in the process of jetting carbs and not having good luck with it.so now i went right through the carbs.the needles are set to the middle notch.then i noticed that my idle screws where all the way in so i backed them out and resynched the crbs and it seems like the idle screws do really do any thing.this is on 35mm pwks.what would cause the idle screws to not work

if they are the stock plastic idle screws they may not be long enough. try cutting down some of the springs so they will go in further. also it could be that you are too rich on the pilot. try backing out the air screw see if the idle increases

ok so now im giving up on the jetting cause i think i have a problem some where eles.ive gone rich and lean with jets and it does the same thing.the problem im having is it seems like its running out of fuel or its loosing spark.im setting up for circle track racing and when i try to go over half throttle it has a bad bog and then it almost seems like it drops to one cylinder.i dont think its fuel cause im running pingle valve and these are 35 pwks.it also seems that the right pipe is colder than the left like its not firing.thats why i think its the electrical.i need all the help possible.

Have you checked the clearance between the pick-up coil and flywheel should be .020 might be wrong on that its been awhile, I would test stator, ingnition coil, might be your c.d.i going bad. It would be a good idea to double check your stator timing.
