Pull the float bowl and float bowl gasket off the carburetor.
Place the carburetor upside down and let the float rest against the float needle.
Measure the distance between the gasket surface located on the bottom of the carburetor to the edge of the float. On a 24 mm Mikuni card, the distance between the gasket surface and the float should be 1 inch. On a 20 mm Mikuni carburetor it should be 7/8-inch.
Bend the metal tab on the float that rests against the float needle. Bend it towards the float needle if the measurement is shallow and away from the needle if the measurement is too much.
Use a pair of needle-nose pliers, making very small adjustments to the metal tab and then recheck the measurement.

I believe it is near the bottom, around where the float bowl meets the carb body.. You need a straight small screwdriver (Short) facing upward.

Don't worry about the air-fuel mixture. It doesn't need to get adjusted.
