Motorcraft 2150, 2 Barrel Float Circuit
Our carburetor kits usually have more than one option for a float bowl gasket. Place each one on your carburetor float bowl. Pick the best fit. Be sure the gasket doesn’t allow outside air into the float bowl. Also any passage that actually goes somewhere should not be covered. Note that there may be cutouts and holes that are casting holes and don’t go anywhere. They can be covered.
It is OK if the gasket sticks out beyond the float bowl as long as the air cannot get into the float bowl.
Here is an example of 2 float bowl gaskets.
 | Measure the float level at A, from the bowl top to the top of the float while gently pressing down on the back of the float. In the end the float will look level. Find your measurement on the instruction sheet included with each carburetor kit. Can't find your particular application? Pick the engine closest to what you have and use that measurement. |
 | Adjust the float by bending the tab (B). WARNING! Be careful not to put pressure on the needle. It will be damaged and leak. Move the float up and down by hand and see if you feel any catching, or rubbing. The float pin may be worn. |
