Whoa, guys. We are still talking about NGKs, right? With NGK a smaller
number is a hotter plug. If a 6 is too hot, a 5 is worse.

Thanks, I will try a 5... Any suggestions for an air-fuel meter? Never had
one before.

Actually, I agree with Dan - a 6 is
fairly warm, but you can try 5's (I have 8s on my race car, 6 on street). I
missed the 35 deg advance before also - that sounds like a "leave it alone"
number too. Normally, the timing advance compensates for the lack of oxygen
and its slowing effect on fuel burn. Same with lower octane gas. The
air-fuel
meter will be the real answer, and you can do things gradually.
