The quickest way to choose the correct carburetor is to measure the inside diameter of the engine side opening of the old carburetor. Then choose a carburetor of similar size.

At this point just measure the overall height, width and depth of the carburetor to make sure it fits.

Be careful not to choose a carburetor based on the size of the engine displacement. This is only a reference, not a standard.
