so I'm having a heck of a time getting this engine to idle decent. Seems way too rich. Plugs are wet, inside of intake usually looks wet. It's 383 stock eliminator engine. It has 7-9 in. of vacuum at idle. The carb, R4668, w/vac secondaries, came from a carb guy with a 3.5 PV, I put a 2.5 in there, and it may have helped, not sure. So at this point I'd just like to get it out of there and see how it responds. The mixture screws seem to work right, and all butterflys have had a hole put in the them. Secondary block doesn't have a PV. Also the motor seems to run lean at WOT, this was seen on the dyno, 13.2, and inside of headers are white.
