Well I already have a ridge reamer, a hone, and a ring compressor/sleeve. I'd go the $50 route and put her back together, just my opinion.

Either spend the $600 and get her done right or go with what you got.

Bore and hone and valves and crank turn, gaskets, new rods and pistons and rings, new governor, etc....without pricing it...my guess is around $600 and you do the work.

Bear in mind also these do have a reputation for losing a governor and when they go they take the whole motor with it.

$50.
