These carburetors use plastic floats. If carburetor is to be disassembled and the wells sealed and quad rings replaced as suggested, an additional suggestion would be to replace the floats. Plastic floats gain weight with time (there are weight specs for them) but replacement is cheap insurance as they can be just as much of a problem as are the wells and quad rings.
