Hmmmm....how did you type those weird letters? 

- Either way, get a torque wrench and tighten them to 12 ft. lbs.
like most of everyones saying it sounds like an airleak quickest way to identify an airleak would be to start engine up let it warm up and spray carb cleaner around the carb and intake wherever u hear the engine idle speed up at thats where the leak is also let it warm up and turn choke on if engine doesnt die immediately u have an airleak most common place for airleak is around the intake manifold where the carb slides if thats where it is take some permatex high temp gasket maker and seal it best way to do this is to take off carb and manifold clean both with alcohol make sure theres no oil or gas in it u want it clean as possible then take gasket maker rub a little around the manifold slide area making sure not to get it near the very end slide carb onto manifold and wait to dry
so it would be 144 in lbs, or is my math wrong?
i say you have no spark...first i'm in for the beer...and i'll pay the shipping...now we have three areas to check...cut off switch..cdi...magneto...first take off your magneto plate and check wires...connections...than follow your blue and black wires out off the engine and check these connections...tape off the white wire..if you have a headlight we'll connect it later...remember...blk to blk...blue to blue...thats it...do not hook up the kill switch...now you are wired direct..check plug...gap between .24 and .30...now does your bike move freely or do you have to pull the clutch in to move it...if the later...fine
..put your muffler back on...go out and start it...by the way what kind of carb do you have?one thing at a time from here...we must do it this way or its a hit and miss...get back to me . Dennis...i,m going for the beer...ha
