Carb choice for a mutt motor.

I certainly appreciate that info. I am a little too advanced I believe. It doesn't seem to surge or buck on trailing throttle when retarded to 7° initial.
I won't be doing anything until I get a mechanical oip pressure guage installed. Drove to the local non-ethanol fuel supplier this morning. The dash oil pressure guage dropped out. I stopped, messed with the sending unit. It came back up momentarily then dropped off again. The coolant temp guage remained consistent, I had already driven far enough that if there was any damage to be done, it would have already happened. Gotta love 50+ year old wiring on anything.
