So when I took the cylinders of to replace the base o-rings, I was surprised to see the the rings including the pool scrapers we're more lined up than I thought they would be.. Keep in mind there's only 20k on this motor... It didn't smoke and the compression was good.. I tested it before the year due.. 178 front and 170 rear..... Always good info to have...
