Thanks for the update, Peter. I rebuilt a Honda GXV120 engine a few months ago to eliminate a big-end knock, but that was a Honda, plus I wanted the engine for a specific purpose, and it only cost $5 for a bucket of used parts to do the job. Personally I'm not attracted to side valve engines, though non-Honda OHV ones are at least a bit interesting. Hence I'd have made the same decision you did on this one.

There are lots more interesting engines out there, and I'm sure you'll continue to find enough of them to satisfy you.
