My son has an older pw 50 1981 yamaha. It runs prety good but it dosn't rev like it should. I think its over fueling and i've had carb apart 100 times. Just wondering if somebody could help get this thing reving up properly

wich one is the air fuel mixture, i'v been playing with just about all the screws and it didn't seem to make a diffrence.
And if take the head off is the head gasket going to be screwed or is it reusable?

make sure the gasket from the carb to the head isnt sucking air.
