Carb tuning, larger accelerator pump nozzle?

Rat,
Can you read? Your statement, post 69: "A smaller MAB will start the mains sooner".
I said the same thing waaaay back in posts 39, 57 & 67.
And there is nothing wrong in my post 67, which you claim in your post 70. In fact you are contradicting yourself.

My bad. You bark so much crap it’s hard to keep it straight. A bigger MAB will start the mains sooner and be leaner at rpm. A smaller MAB will delay the mains and make the fuel curve richer at rpm. It doesn’t matter who wrote the book, if you think a bigger MAB will delay the mains you’ve never tuned with an O2 sensor. You can watch it happen.
