Thanks for your thoughts. It may be a problem finding a place anymore in the area that will
bore a small engine. Perhaps a motorcycle dealer?
The local Napa use to have a engine machine shop…… long gone.
One of our members, Dan Anderson can help you I’m sure…He is in Tn, so the block would need to be shipped there… And yes, I agree, bore just the bad cylinder….But do try to find an updated standard piston/rings for the good hole…
