Screwing This In Will Give The Engine More Gas Or More Fuel? Thanks In Advance :)

less fuel. You turn it out for more fuel. mine was stock at 2 turns out. I opened it up with half of a turn and felt the difference.

well first things first, if you have a 2 stroke you have an air screw, if you have a 4 stroke you have a fuel screw. On a 4 stroke turning the fuel screw in gives it less fuel and turning it out gives it more fuel. As for a 2 stroke, if you turn the screw in you get less air and richen the mixture, and for a 4 stroke turning the screw in would give it less gas, giving it a leaner mixture.
