I figure, with a little effort those engines can be usable. The one I had worked. It just was really loud and vibrated too much. The clutch was a real weak point.
That’s why I was asking specifically in the original post about the engine w/ centrifugal clutch. Not the bump-start 1 speed ones.
I haven’t seen one of those critters, in person, and it sounds like nobody on here has either.
