Thank you for letting me join your group,I am amazed at what I have seen so far on this site.I have a 1976 Champion compressor need some advice ,it runs but will not build up air,I removed the back cover and water pumped out,the same thing happened when I took out what seemed to be the oil filler plug,more water,The plate with the makers info has Shell 100 on it which made me think it should have had oil,not water pouring out.Any help or advice would be welcome.Thanks,Jay ok
