Joe:
I have found that my B's like to have a large main and a big spread
to the air corrector. Don't ask me why, it goes against what the books say.
I run a 145 main and a 195-205 air corrector.
This is on a long branch manifold on an earlier high comp engine,
your mileage may vary etc. etc. etc.
135 is the smallest I have run, and 145 is the largest. I then
choose an air corrector that gives me the best overall mixture. This has
worked on short branch and long branch. 33-36 mm chokes. I do run pretty
big pump jets, but I can't remember the numbers. You need a big squirt
under acceleration to get rid of the siamese bog tendency.
Good luck.
Kelvin.
