The original gap would have been .003 to .004.
Your measurement at the bottom of the cyl. where
there isn’t any ware shows about .002 worn
off the ring increasing the end gap by .004 to .008.
Your measurements also shows a taper of .022.
That’s a lot. If parts were available you would
hope to straighten the cyl. by boring it to .030 over.
Then with oversized rings and piston it would
run for sure.
I still think it’s worth trying and hope it works out for
you. I find both the ½ & 1 hp. motors fun to run
but the Pal is the first motor I ever ran so I may
be showing some favoritism here. Let us know
how it comes out.
