thanks for the advice. i made the mistake of trusting the book and i had the gap almost twice as wide as needed, weakening my spark and wetting my plugs. i wasnt noticing a terrible lack of power but when i idled for awhile or motored at lower rpms it seemed to hesitate a little(like a fouled plug) until i got the rpms up for awhile. i am glad i noticed the post when you suggested the tighter gap. thanks again
