Can anyone identify this engine for me?
There are no markings on this engine that I can find. ....There is the #63638 stamped on a metal tag tied to the engine, but I don't know how relevant that is.
The decal on the shroud is unreadable.
The engine has exposed valve springs, a cast-iron muffler, uses a 7/8" spark plug, and has a Donaldson air cleaner.
Thanks for any help!
