On my model A/b engines, single 94 or 92 has worked well with currently available fuel disadvantages, with a bit of delay on the enrichment such as a 5.5, which gets rid of the wet plug symptom. The pulses from the banger seems to fool the power valve. On my 59A, the family of Chandler Groves carbs, again in single use, the 6.5 power valve worked OK, but not well observed. I also Model B, ran two 81 Strombergs just as the came off of the 60. Never got rid of the rid of the flat spot that should have been an accelerator pump thing, but again, never got there. Because of the very low price, later Holley/Ford 94s can be a good place to start while Strombergs are mired in that "cool" thing that makes them a different kind of issue. Good Luck: Fred A
