inter .042
high .027

How does it run? Do you have a data logger with O2? Idle bleeds are easy to adjust if needed, if you got a good clean idle and it comes up on the 2 step cleanly. there good!

High speeds and intermediate bleeds are much tougher to tune without and O2 curve, trail and error with some plug reading or a dyno session.

If you decide to tune at the track make a good size change, at least 6 sizes.

Totally agree....except the high side...with two or three circuit carbs, 6 numbers on the bleed is generally about 24 numbers on the jet. I would pull the mid bleed completely out, get the idle and transition right then sneak up on a good plug reading with progressively longer pulls until it looks safe....then use the mid bleed as a fine tune feature.
