I USED to be a fan of OS engines, I only bought OS, no matter what the price. Problem is, every one of them peeled its cheap nickel lining very quickly, even though I ran good quality oil fuels and always ran rich. I grossly overpower my planes, so the engine is usually not operated at full power for more than a few seconds.

When I found out that chrome was much better than Nickel plating, and that OS did not use it to save a few bucks, I was pissed. OS cost me hundredes and hundreds of dollars in replacing engines just so they could make a few extra bucks profit by using cheap nickel instead of chrome. I am very angry at them, I hope word gets arond so that no one buys thier engines. It is well known that OS engines peel thier linings yet they do nothing to fix it, although they will sell you a new piston and liner for almost the price of a new engine... I have no use for corporate greed and I dont think they deserve to be in business.
