Update:

Installed the 6.5PV, doesn't lean spit at low rpm, only mid rpm.

Installed the 69 jets on the primary block. Didn't do much, drives a liiitle better.

Leaned out the idle mixture screws, discovered something! The idle mixture screws have a big effect on cruise AFR. So before I drill out the PVCRs, which I almost did today, I'm going to richen the main jets while leaning the idle mixture to see if I can get it rich enough not to spit without dropping below a 14.5 cruise AFR.

I can see the light, and hopefully I can leave my drill in the droor.
