The engine may not work on its side. There are issues with the oil sump
and fuel tank and carb.
You could try getting a cheap/free centrifugal clutch from a chaiinsaw and
try it. You would not loose anything.
In my experience, I have only got drive belts and pulleys to work with
vertical drive shafts.
Best of luck with it.

>>> My question is about centrigal cluth. I have an old 2 strokes lawn mower engine, it's not very powerful, maybe 2 or 2.5 hp. It doesn't have really high rpm but I can increase it a little bit by pulling on a spring. Will this type of clutch work on my engine? If you have documentation about this subject, could you send it to me?
