    Don't buy it until YOU see the results of a compression test on the top cylinder. Should be at least 130 pounds (150 preferably). A half dozen or so of these have come through my shop, and only one had a good top cylinder.

    PS: If you do buy it, let me know. I have tricks to keep them alive.
