Marvel-Schebler Carburetor Bushings

The carburetor on my TO-20 has worn bushings for the “butterflys”. Are there parts or comprehensive kits available for Marvel-Schebler carburetors that include these bushings?

Yes, many of the deluxe carburetor kits come with bushings, some even come with bushings for the choke shaft as well as the throttle plate or main shaft. There is a special jig for installing the bushings that most dealers have but you can also carefully ream the carburetor body to fit the shaft. The special jigs are particularly helpful when the wear is excessive. You can also purchase the bushings separately from some after-market suppliers.
