Stormin Mormon fired this volley in
news
Today (Saturday Sept 14, 2013) a friend gave me an
air compressor. Says when he ran it six months or
so ago, ran fine. Sears oilless, 12 gal tank. Said to
deliver 3.3 SCFM (think that's right) at 90 PSI.

Fooey... It couldn't be both Sears AND 'ran fine'.

Stormy, 3.3 SCFM isn't enough for anything but an airbrush.

Junk it. Keep looking.
