INAT idle stop screw without venting valves
I have a 72 250 M130 US with the original Zenith INAT 32/40 carburetors. The
Haynes manual states that the gap of the idle stop screws is supposed to be
2.3mm and stop at the float house venting valve. Unfortunately 72 onwards the venting valve was removed and replaced with a screw.
on a just rebuilt carb, what is the preload needed for the idle stop?
