All you should need are new leather primer seals and instructions with diagrams on how to replace them. If so send $10.00 cash (no checks or MO’s) and a self addressed stamped envelope to me: Lloyd Lautner 9289 North Long Lake Road Traverse City Michigan 49685
Haven’t ever seen a carb kit for this model. There are only a few replaceable parts. The primer seals that LLoyd addressed, The cork float, which may or may not need replacement depending on it’s condition, they can sometimes be lightly sanded and recoated. The top gasket, which can be made or bought NOS, and the gasket that meets the block, if you choose to remove the integral carburetor/intake/exhaust.
