The 1949 is a single year; most parts are unique, and VERY expensive!

1941~1948 are virtually the same carburetor, and all parts are interchangable, and relatively cheap.

There are some rebuilding kits on ebay which say 1941-1949, but they will NOT fit the 1949 carburetor.

Good carburetion is fuelish hot air
The most expensive carburetor is the wrong one you attempt to modify.
