More accurately: would it be worth anything if it's not broken,

Nameplate says "Emerson". I'd be using it mostly for filling tires
and painting model airplanes.

Update:

When I bought it I made sure that it got plugged in and came up to
pressure. What I _didn't_ do was bleed off some air and make sure
it started again -- which it doesn't. It tries, but the thing don't
turn. I thought "this thing needs a blow-down". Then I heard the
slow leak from the compressor head, deduced the existence of a check
valve, and found the check valve. Presumably it just needs to be
're-checked'.

Oh well.


If it runs and pumps, the rest is fixable.

(If it did not run, it could be fixable also, just not a given) i

Yup. It looks like the check valve is even made to be maintained, so
I may be able to fix it without either total disassembly or buying
replacement parts -- this is a good thing, because the compressor
purchase has inspired purchase of spray guns, hoses, etc. -- I just
need a regulator and to clean up the nice used guns I bought, and I'm
ready to paint.


I do not think that it is the check valve that is the culprit.

Unloader stuck?

It's a cheap little compressor, so I'm pretty sure that the "unloader" is
an intentional leak in the compressor head and the check valve.

I respectfully disagree with Iggy, but if the check valve is doing it's
job I may well come to agree with him.
