Factory setting of the fuel screw (not an air screw) is 2 1/4 turns out from lightly seated
It controls the amount of fuel mixed with a set amount of air metered through the passages in the carb body - turning it out makes it richer and turning it in makes it leaner - 4 to 6 turns out and it is not doing anything - what ever fuel is metered into the idle circuit at that point is all pilot jet - adjusting the fuel screw has to be done with the engine at normal operating temp with fresh fuel (93 octane non-alcohol blend is preferred)
I would suspect the carb - sounds like it's trying to idle on the main jet - why did you clean the carb? What was it "boiled" it in? If it was water, then it did nothing except make it hot
