Well, after 50+ years of reliability, she finally spit the bit. Just rebuilt the carb and while
pulling recoil snapped off crankshaft. The elusive 33080. Anyone know if there is one
out there somewhere? Or perhaps a technical drawing.

Unfortunately, that part is pretty much a "unicorn" as far as availability...
A couple of choices immediately come to mind:
1. Purchase a used beater donor HS-40 engine or short block and canabalize the crank off of it for your engine.
2. Possibly, a good machine shop could fabricate, die (thread), and weld on a new "snout" on the end of your crank?
Either option will not be cheap!
**Edit: I have always thought that the threaded crank end appeared to be puny and weak. It "concerned" me every time I installed a Tecumseh flywheel and torqued down the flywheel nut to specs, that I could possible twist off the end of the crank in the process...
