4:32 Set your drill torque setting to #1. That way if it gets away from you the tool will provide some over torque protection. You're going to tear some stuff up otherwise. Idle speed. 1:09 There are three screws on the side of the carb. Top Left Black (H)= High speed fuel mixture Top Right Black (L) = Low speed fuel mixture Lower Large Silver (LA = Idle speed Warning. If the carb is set lean you will burn the engine up. With a warmed up engine open the throttle wide open. You adjust the H screw looking for maximum RPM's. Then you turn it 1/4 turn counter clockwise. At idle you may have to adjust the L screw to get a smooth idle as you reduce RPM's.
