Another source for rebuilt 235's is Jasper Engines, www.jasperengines.com. They say they sometimes have rebuilt engines in stock, but you will probably have to provide a core; I did. I know a guy who has 6 or 7 235's sitting in the grass outside his barn. Jasper gives a 3 yr/75,000 mi. warranty on their rebuilt engines.

Don't read the directions, that'd be too easy.
