replacements for Tecumseh snow engines?

[BLES]

Does anyone have a reference for replacement engines for no-longer-available Tecumseh's?? I live a heavy snow area and there are a lot of dead Tecumseh snowblowers. The last few I've replaced, I was lucky(??) enough to find another Tecumseh still available, but those supplies all seem to be dry now. VERY time consuming trying to measure/compare/cross and I still haven't found one this time. Any help would be greatly appreciated.

Tecumseh LH358SA - 159630A

This engine is labelled 10.5hp but appears physically smaller. Looking for replacements. It's on a like new-barely used blower so I'd like to find an option.
Thanks.
