Re: How do I get Idle speed down other than idle adjust screw?
One thing I found when I took the whole throttle/carb apart was that the ends of cable were solid without adjustment. When looking into the intake end of the carb, I could see the "Barrel" was set too high. The only way to lower the barrel was to trim about 1/16" off the throttle stop inside the twist grip. As soon as I put the whole thing back together, I could adjust the idle with the set screw. The bottom line, the cable length was too short!
