It is running overly rich right now...enough to continue to foul plugs. Should be having this taken care of early this week. NGK TR55's at .048" are what I was running.
I am having a problem figuring out the best plugs and best gap.
What are guys successfully running??
What to avoid?

So no one has a stroker? :lol:

i would close the gap to .030.

i would close the gap to .030.
Could you explain why?
That seems WAY small.

tighter fire, less chance of fouling with the excess gas
