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??

note that the pressure pulse carb document (previous post) refers to the original carb that had no venturi, most of the pressure pulse carbs used on mac engines had a venturi.
Here is link to BDC-14 spec page:

..and the old duck bill article:

and of course you will find all the carb part explodes included in the engine IPLs on this page:

These carbs tend to be a little touching and more difficult to tune than the Tilly carbs, but I like to use them on my macs since they were the stock carbs.
