Hi Ed
Isn't it funny, I've never had a problem with the OS40 FP. I've had two, both bought second-hand and both ran well. One had a slight castor stain on the cylinder. In an attempt to soften the oil prior to cleaning I put the engine in the oven. I then forgot about it. When I took the engine out of the oven, the oil had gone but so had all of the silver paint which OS use to paint their engines! Yet it still ran well.
OS does NOT paint their engines except for the blue LA series. The Gold and Blue heads were anodized. None of the FP series were painted. All natural aluminum.
