I bought a Westbend / US820 Power Bee with a cut off crank the leftover stub would only be 1/2" long
What was the use or reason the crank has had the PTO shaft lopped off ?

Bob,

Most all West Bend engines were made for industrial applications and they continue that tradition today so if the crank end was not cut or broke off you have a power plant for something other then a kart.

Pretty sure the 820 was used on generators, water pumps, jaws-of-life and many other applications.

Don't have a lot of experience with 820 industrial engines so not real sure what their port layout is. Is the port layout on your engine the same as a kart engine or does it have blocked off ports similar to a McCulloch saw exhaust port ?

A crankshaft swap and some minor port work might be all you need for a kart engine conversion but if your using the engine for something else the stock porting may work well for you.

I had one a few years ago that had the clutch hub irrevocably frozen onto the crank. It also had an Akkerman oil housing between clutch and engine. The only way out was to cut the crank and replace it. This could be a reason your engine has a stubbie. TJ

Ultralight motor

Don't think so as then there would be nowhere to mount the prop drive boss if it used a reduction drive

It's funny the shaft has been cut as now the engine is useless but in my case I bought it to get the cylinder as my old one had busted mounting bosses so now I have a few spares for future rebuilds

No blocked off ports and the port layout is the same as the rest of the 820's I have seen

Biggest difference I have seen is the rod and piston assy

Props were mounted on the flywheel side by means of a hub .
Some had the outer air shrouds removed and the fins on the flywheel shaved .
No need for a PTO.
