The compressor runs (rather noisy) but the

Please do not take offense to anything I say but your compressor because it has nothing to do with you. It's a personal grudge against that particular air compressor and the Air Compressor Nazi's that designed and built it. It is a piece of junk, and that's the nicest thing I can say about it..

The model you have was built for one thing and one thing only. It was to get an air compressor into the hands of customers that never really needed an air compressor for anything more then inflating a tire or a basketball. My friend's mother bought him one because, as she put it "it was cute".

In all seriousness it is a throw away air compressor. I have seen several go bad with less then 30 hours time on the pump and motor. If it is bad and from your description it sounds like it, there is nothing you can do about it. Impossible to get parts for unless they come from another one of the same type.

I'm sorry that I can't be more helpful. What I can say is you are better off to replace it. There are plenty of similarly sized and priced compressors that are far superior to the 3gal. 11/2 hp craftsman. The Senco PC1010 is a great compressor for it's size and specs.
Good luck
