Hi

Sherco ST 125 carb air screw.  How many turns out would be a typical setting?

Thanks

    Delorto is a fuel screw. Out = more fuel. Looked into this and found conflicting advice. Some say 2 and a half. Some 3 and a half. Currently mine is 3 turns out. New jets on the way for tuning. Get a bit flat 2/3 or so throttle.
