remove or replace. Now remove the float assembly which will consist of
If the carburetors have been recently used, there will be gas within the
float bowl. Gas does not need to be removed as it will not leak when you remove the main jet. The main jet is at the bottom of the float bowl. It can be
removed with a flat head screwdriver, turning it counterclockwise.
To install or reassemble, follow above directions in reverse. Make sure to
remember to install the float assembly (as I have done this once or twice!!!).
