Its not just gas.....I bought an electric air compressor....same thing. It ran for about 30 seconds and quit. I took it back to the CrappyTire store and they told me I would have to ship it back to the supplier (Texas..)at my cost AND I would have to pay for the return freight. They figured it would cost me about the same as buying another unit.
Since I didn't have a warranty I torn it down and figured out what the problem was.
And the nail gun that was included with the compressor.... lasted for 15 nails.
I don't buy near as much from them as I used too. But when I am in there I warn people that they need to ask about the return policy when I walk by....even if they are with a sales person.
