I'm not saying all the other things I tried didn't work, but understanding how big a deal timing is, finally got me running cool. I'll keep my shroud and all the other things, but timing turned out to be king for me.

What were your timing numbers? what initial? total advance? In at what RPM? Is your vacuum advance MVA or ported?
