Carb gaskets MC2100

I have a very noticeable vacuum leak under my carb. It is a Motorcraft 2100 (The Chinese carby carb knock off from National Carburetors). I am using a Felpro 60716 space and purchased what I thought was the correct gasket to fit between the spacer and the carb. There are two gaps however that the spacer covers but not the gasket. Please look at the attached pictures, I can't beleive this is right. Does anyone know the proper part numbers , if any, for gaskets to fit between the spacer and manifold, and the spacer and the carb?

Pretty common problem. Motorcraft changed the footprint of the 2100/2150 carbs for some unknown reason, causing a major vac leak if you get a mismatching gasket.

Sorry, I donít have the proper gasket #, but Iím sure someone will.

Good catch and good luck.

it is very easy to buy the gasket material at the local auto parts store and cut it out yourself To fit correctly.
