Stop in for a cup of coffee

We just chatted. Thinking adding a bit more total will help. Really think it is really rich though.
prolly yes on both.

Could try going to 38*

It's got an MSD RTR so limited on the curve.
Advance is probably a straight line.

It should be OK to finish with the carb experiments.

It might be best to slow the mechanical advance a little so its not all in untill 3000 - 3400 rpm, maybe 38* when the vac advance is connected.
