Got a chance to rebuild the compressor with the bagpipingandy kit, the cylinder walls had some dirt inside possibly from the old ring grinding against them.
All good, much quieter, works as it should.
I should say my compressor ran just fine, a little on the low side as far as pressure goes, but I didn't want to let it fail so I did it as a preventative thing.
Daughter helped too so that was a plus. She really likes turning wrenches and she's only 3.
