Walbro Carburetor for Tohatsu MP 472, F100 GC Multi-Purpose Engine & Others Carburetor # WB-37-1 Before gasoline makers started adding ethanol to gasoline, rebuilding a carburetor was a repair that was rarely--if ever--needed. Since the ethanol in gasoline breaks down the gaskets and other rubber components in the carburetor, these days you will find it necessary to rebuild your carburetor when the parts become cracked or brittle. A well-maintained carburetor will only need a rebuild every few years when the internal components begin breaking down.
