It will be the largest obvious screw might have a knerled outer head to make it easy to adjust with your fingers, turn it in to raise idle, with a spring on it from memory, not the small one.

Wouldn't a stuck open hot start cause way high idle also.?.

 

That has been my experience. Happened to a buddy of mine last sat. The hotstart was stuck partially open and the idle was high. He pulled the hotstart from the carb, cleaned it and the idle went back down. May be worth checking....
