1. It depends on what you mean by "proper" - original, or any carb that will fit
2. Someone might know if the Canadian carburetor was the same as the USA carburetor
3.
The USA 216/235 Carter carburetors are listed here. It looks like the same model downdraft carburetor was used on all engines.
Are you looking for an updraft or a downdraft carburetor?
