Need help tuning Quickfuel carb

Cookietruck I am going to try the 68 main jets today and I will report back as soon as I get it they installed and take it a for a drive.
I have the same thought as you as it being lean and when I open her up it will clear up a little bit because it’s getting extra fuel from the pvcr’s below 8.5hg of vacuum.
I think I know why the distributor cap has the odd burn pattern on the cap terminals.
When I first installed my Taylor wires I used dielectric greas in the boots and I think I used too much.
Because I had dielectric grease clear up in the plug wire where the metal plug terminals clips are, some of it was wedged up in there creating an obstacle for the spark getting to the plug.
When I removed all 8 wires and cleaned the boots out by spraying small blasts of carb cleaner onto a q-tip and re-installed the wires it got quite a bit better and felt smoother.
Prior to cleaning the dielectric grease off the wires the missfire would show up around 45 mph in 3rd gear.
After cleaning the wires the missfire didn’t show up till 55-60 which is about 2500-2600 which right about where the mains start taking over.
I think my mains start to take over around 2300-2400.
So I will install the 68 jets in place of the 65s and cross my fingers that it works.
