Unfortunately, my plans hit a snag. I had the compressor checked out by Rix here in San Diego and two of the aluminum heads are apparently pitted. The quote to repair is prohibitively expensive. Is there a market for parts or is anyone interested in a project? I am significantly underwater at this point.This is extremely helpful. Thank you very much. I am pretty confident that it is not seized up and that it just needs some attention because it has been in storage for a couple of years. I will pull it apart and see what things look like. Again, thanks for the input and support.
