How to Adjust Carburetor Floats

201

Step 3

Locate the fuel reservoir tank on your carburetor and remove the bowl by unscrewing it from the top of the reservoir with a screwdriver. Carefully pour the fuel that is in the reservoir into a gas can.

Step 4

Turn the carburetor upside down so that you are looking at the float from the bottom. With the float seated flat against the needle valve, use your fuel level gauge and measure from the bottom of the float to the mating edge or bottom of the existing reservoir bowl with the bottom off. Your float should be set at 16 mm.

Step 5

Verify that your float is at least 16mm from the bottom to the edge of the reservoir bowl. If it is not, use the needle-nose pliers to carefully bend the float tabs and recheck the measurement. Do this until the float is at the correct setting.
