Start with the needle jets about one and one half turns out , start engine and adjust to

to smooth running after engine temp is up to normal operating temp.

Ted,

Assuming this is a Marvel TSX464 Carburetor, I usually go 1 1/2 turns out from stop on the air/fuel and 1 turn out on the enrichment needle for a starting point. All engines are different and are going to need adjustments accordingly. HTH
