Default every so often I do get one that cannot be fixed

Mark, Arvin, and Kevin serviced and return shipped.

Poorly resized piston+sleeve sets with Out Of Round conditions it is best to fix it before running, that would have otherwise worn piston unevenly, resulting a un-salvageable piston + sleeve set, or at the very least will not run well or for long. I have found the best repair method-process is to "first" OPEN sleeve bore while reforming cylinder to again a uniform (Perfectly Round) diameter. At this point of repair the piston is very loose in sleeve with NO physical resistance, loose enough to push piston thru top of sleeve. Resizing can be then performed accurately and with a correct tapered fit. I use the same process removing the pinch damage first, with OverPinch repairs.

Just request on my order form "REPAIR" as you would a standard resizing.

Any questions guys just call....
