Not Ranked
Found the air leak. All 4 left side spark plugs not tight. All 8 plugs not gaped to 40. Stupid. Stupid. Stupid. I’ve seen it in print on this site. “It’s not the webers it’s something else.” I drove around and 1/4 turned the mixture screw. I am now at 1 1/2 turns out. No more popping. It’s running good. Not great but good. I have not checked A/F. I hope it’s rich, it feels like it.
I have to fly out of town tomorrow for 3 weeks. When I get back I’ll jump in and continue. Will post my progress. Thanks for the help!
