I ran a number of experiments before discovering my biggest problem was timing. I still need to get my distributor set up, but higher timing made a huge difference.
It's still in pieces, but when I took it apart, I was running super rich. Front two plugs are very black. I'm backing off on things. I'll probably go to PV 8.5, MJ 51 (original). It's a gas guzzling pig as it stands.
Current settings (too rich)
○ Power valve 9.5
○ Main jets 54
○ 35 accelerator
○ Secondary jets 59
Timing now set to 18 BTDC (no vacuum advance)
