The boys 1/3 carbs are insanely lean until we slowly rev it up and start hitting the next circuit.
Idle circuit hole is right at the base of the butterfly valve plate, right? Or does idle pull fuel from any other holes?
Can we chase 'em with a tiny wire to ensure they are clear?

We rebuilt these, but grrrr obviously missed these when we had em broke down.

The idle circuit goes through the hole the adjusting screw is in, the holes under the throttle plate are the mid range.
