Come on now,.......has anyone really ever stopped the "afterfiring" ?
Isn't it really the design more than the lean carb conditions. Mine is now running perfectly, no signs of running lean, nor does the plug show any, and it still sneezes at shutdown, and still bangs quite loud on decelleration. Minimize it a little, yes maybe, but fix the root of the problem,.....not from what I have done or read has been done
