Looking at buying a little Sullair 85 compressor. This is the one with the VW Beetle engine in it. The seller can't tell me much about it since he's never actually used himself. Says it doesn't run. I'm not as worried about the engine as I am about the rotary compressor. I hear these things need the head unit rebuilt after so many hours of use. As old as this compressor is I figure the rotary compressor will probably need gone through as well as the engine. What am I looking at as far as parts availability and cost in dealing with this thing. Just wanted to use it as a sandblaster.
