I have a question for those who know more than myself. I am curious the average size for a pilot and main jet in a 24/24 carb while using a polini barrell with expansion chamber at sea level. I am gratefully for any insight you might be able to offer.

I'm running a 24/24g carb and with a Sito+ and running a 50-100 idle jet, 120-BE3-135 main stack. I'll be getting a used prima expansion pipe in the mail this week, so I'll be playing with the jetting

The only problem he hasn't run a stock carb in over 20 years and doesn't know if what i am using is right.
