Ive been over this thing with a fine tooth comb. replaced all the top end gaskets because they were weeping, cleaned the carb, made sure and double checked timing, both cam and ignition, used the shop manual and tested each component of the ignition (except the cdi box) and yet this keeps happening. put a new plug in, start it right up, warm it up, take it out for a drive. as soon as you rev it up a little, it kills the plug and you might be able to keep it running for a few minutes, but probably not. this is getting expensive! taking a plug out and cleaning it doesnt fix the problem, yes its a little sooty, but i have to have the thing warmed up before i can tune it, and so far, i just have to go by factory specs until i can get the carb dialed in.
is there any help out there for me?
