Thanks Destroyer. I'm wondering the same thing - the readings may not mean a whole lot. I would guess that any lubrication on the piston rings is long gone by now, and with that there is not a good seal. There's likely a coating of rust on the walls, too. But I have no real experience in this area.
If I could, I would drain all the fluids and the gas (two year old gas is still in the tank) Then I would get some lubricant and squirt it down the spark-plug holes and turn the engine over a few times to work the lubricant in there. But since its not mine, I can't really do that. And if I did (or the seller did), would the new compression numbers be useful, or would they give me a false sense of security?
