turn the pilot screw inuntil it just stops at the seat. Be careful to not over tighten it, it is very delicate and can break. Then turn it out 1 and a half turns. With the engine warmed up turn it in slightly until the engine just stats to sputter, then turn it out until the engine starts to run smooth our turn the pilot screw out from the 1 and a half initial setting until the engine RPM just starts to increase the turn it back in a hair bit to where the RPM just starts to come down.
Good Luck
