In going thru my remaining stock, selling on eBay (eventually hundreds of parts) under my "sellers" name (Joe_OMC32) should you want to check it out... I came across one new and one used 15hp (I think) carburetors. The part number of 390773 indicates they're 15hp carbs, but I'm still not sure as I could have stuck them in the wrong box (or a old box), then forgot about them.
Measuring the venturi, actually the hole in the back of the carburetor where it meets the intake manifold, I come up with approximately 15/16"... perhaps just a hair over 15/16".
Does anyone know the the sizes of the (rear) venturi/hole of the 9.9hp in comparison with the 15hp? If so, I'd appreciate having you pass it on to me. That would pin it down for sure.
The confusion arises due to the 9.9 "Sail" carburetor and the 15hp "Sail" carburetor being the same.
