I am restoring my grandfather's Witte headless 6hp engine (my first hit 'n miss experience, and this is my first post as well). It appears complete except for a missing carburetor. I have contacted www.hitnmiss.com but they do not have one. Thus far, I can't find anyone who has one. Can someone tell me if the carburetor has to be from a 6hp or were other horsepower engine carburetors interchangeable? Of course, if any of you have a carburetor for sale, please let me know. Thanks in advance.
