Thanks for the replies. Very helpful group.

I figured it out though. What appeard to be no fuel was EXTREMELY rich. The way cool exhaust temps were what kept throwing me off. The solution was really pretty simple and I'm frustrated that I didn't see it earlier.

I decided before I swapped carbs around I'd change to a hotter range plug. Boy did that wake things up, I was so rich that I had some serious header temps once the plugs were capable of burning the fuel, glowing red on the #3 after 2-3 minutes at 2000 RPM. Dropped down to 60 idle jets all the way around (still with 120 holders). Started with the A/F mixture screws at 7/8 a turn out, ended up with all of them between 1- 1 1/8th out. Noticible difference when you try and lean it out just 1/8th turn, starts to spit at you and exhaust pops.

Finally got it out and drove it some, the main circuit was nearly as goofy. It was set up with 120 correctors, F7 tubes and 135 jets. The result seemed to be a rich stumble in transition and pretty fat on the main. Ended up playing around and now have 190 correction jets and 145 mains sticking with the F7 tubes and it seems to like that a lot better.

Bottom line is I'm still a little fuelie on the idle circuit but it is managable for now.

One more question though. After I shut the engine off, maybe 2 minutes and most of the carbs have fuel sitting on the butterflies. Is this like a Holley and an indication that the float levels are still too high?
