I’ll suggest something I’ve seen somebody else do in irder to get one of the Cubs to start.
Try injecting a shot of 90 weight gear oil into the combustion chamber through the spark plug hole, then try starting it, and run with 8:1 oil mix.
The compression on these motors is usually marginal, and the heavy oil helps seal the rings better for starting. Once its running, you will probably be OK…… until it quits or you shut it off, then you might have to oil it again.
Good luck with it eh.
best,
