So after trying to tune the carb yet another time, I still wasn't able to get it to idle well without increasing the idle screw beyond 1.5 turns.
Just to check something before going any further, the ported vacuum shouldn't really have any vacuum when at idle correct? If so then I'm good. When I pressed the throttle the vacuum seemed apparent. Just want to be sure I don't have a vacuum leak. The idle vacuum from the mani was definitely there and strong at idle.
I pulled the #1 plug right after a good run on a warm engine with normal driving and WOT in 2nd, third and fourth gear. This is what is looks like like.
Here are the specs of the carb right now:
Primary/Secondary
Air Jets: 170/180
Main fuel: 140/150
Primary Idle: 60
Secondary Idle: 50
double pump jet at top - 50
From the link above, it seems that it is a lean condition overall. They also state that it could be from an overheat of the head, but the coolant temps seems to be spot on. What are your guys' thoughts on this? I actually expected the engine to run a little rich after finding the jet #'s, but that does not seem to be the case at all.
