Attachment 117336I have acquired an older semi-restored Cub 100 that a friend of mine had sitting in a barn for many years. It has the Kohler K241AS, spec #46270C. Engine spins freely. I'm just getting to the fuel system now. Carburetor is a Walbro WHG, model #4705387. Is this the correct carburetor for this tractor? I have carburetor mostly cleaned but don't know how that main jet and seat come out. The carburetor bowl, needle with rubber tip and plastic float look fine. Would anybody know the rebuild kit for this or can I just get away with a new O Ring bowl gasket and give it a shot? I am attaching photos of the carburetor and the tractor.
