Hi! I have a Tecumseh snowblower that needs a carburetor. I'm pretty sure the model number is H50 65173H. When I say pretty sure, I mean I think the 3 is correct, but it's worn down and hard to read. I have the carburetor off, and the number I find on it is: 110 8F24. I've tried a google search, but the carburetor numbers are all CA65XXX. How do I determine which carburetor I need? I've already tried a rebuild kit, but there's too much corrosion inside. Any and all responses will be greatly appreciated. Thanks.
