Shakymike,
The original governor as well as the carb was originally produced by Solex and has not been available for years now. There was a conversion kit to change it to Impco but the Hoof governor company went bankrupt and no one has produced the S100 governor that is needed to do the conversion to Impco. Try giving Century Fuel Products a call they may have a conversion kit using a different brand of governor. 734-728-0300
