Why the taper shaft?

After much searching for info i thought of a simple solution. I have a fairly good size lathe in my shop so i pulled the pull start assembly from the
engine and underneath it there is an approximately 3 inch diameter metal hub. Set the whole engine up in my lathe, put the hub in the chuck.
Put the tapered shaft end onto a live center on the tail stock. Put a couple wood blocks under the engine so it would not rock. Pulled the spark
plugs out, put the lathe on a slow speed and turned the shaft down to 1.0 straight shaft. Simple setup, came out perfect. Same idea could be used
on any other tapered shaft engine. Maybe took an hour once i figured out how to do it.
No engine teardown, no adapter needed !

Sounds like a workable fix, thanks.
Did you cut a keyway into the shaft too?

Sweet!!!!! I sure would like to have seen that. I don't suppose you took video or pictures, did you?
Set the whole engine up in my lathe, put the hub in the chuck.
I bow to your ingenuity!

Never thought of that Jim! Even in my 10" South Bend, If the oil pan was dropped, most small engines would fit right onto it. Great thinking Jim!

to my milling machine and running the engine and the mill at the same time. Did not like that idea to well to even
I did mill a key way in it later for the lovejoy.
Here is the 446 i saved from the junk man that was missing the engine. Had a sleeve hitch and hydraulic PTO on it.
I made some new hubs and bolted on some 22 inch tall tires on 12 inch rims. Currently being used strictly for some
wood hauling and powering a 8000 lb hydraulic winch to pull the logs to a landing. Its weighted down well, home made
100 lbs per axle on the rear and a 130lb weight bar bolted to the frame above the snap fast hitch on the front so i can
still use front blade etc. Does push a snow blade good as well, has a 1 inch thick rubber cutting edge on it,
