I would like to thank Jeff Stamper and Jeff Campbell for their constructive information about the McCulloch carbs. Thanks to that I gained a lot of dates and found a BDC 16 - double pumper - which I can use for my experiment. Gr. Ben

I am looking for a reed carburettor of a MacCullogh MC91 kartengine. In my memory this carburettor has a very big diameter - approx. 35 mm / 1,5 inch. Fore sure much bigger than other kartengine's in the '70 years. Who can give some info?? Diameter connection, diameter venturi, fabricator??
