Idle speed is set by the idle speed screw on the driver's side of the carb.
So that screw doesn't have anything to the do with throttle linkage then? Because I noticed that if screwed in all the way, pushes the throttle lever back. This would be my error when adjusting the idle speed and timing by ear last summer. I was messing the idle mixture screws more than the idle speed screw. I will mess with this next then.
