I got it out this morning and took the hose off. Turned it right side up. It sparked, started up and blew a bunch of stuff out the piston outlet. It still doesn't try to pump up to the 15 pounds that it should when you turn the key on. I can barely blow through the hose in both directions, so I think the check valve may have some garbage in it. I'm going to replace that too. I still need to figure out why it doesn't pump up when I turn the key on. Rick
