zerowick, you can check your spark plug.

jimk72, what's an apex?

 

Its an attachment to use screw bits in a drill, it magnitizes the tips so your screws will not fall out. Basicly I use the tips that go into this and any multi tip screw driver. Its small and I can get it right up in there and adjust it.

 

ya that is what i use works good

 

Yeah, that's really the best way to dial it in, do you think the NGK's are better than the Champions? Might as well change 'em while I'm in there.
