Try 1.5 turns out for the slow speed (top) and 3/4 turns out for the high speed.

High speed jet is a calibrated hole.----No adjustment.-----Why are you cleaning the carburetor ?----What is the motor doing / not doing ?

Motor fired when I bought it a few weeks ago, guy had it running in a barrel but he kept pumping primer which told me fuel pump was weak, got it home and wouldn’t start. So I got a fuel pump kit and carb kit, fuel pump diaphragms were deteriorated, and when I got carb off the bowl was dry, low speed needle packing was split so tore it apart to rebuild
