I liked the first several minutes of it, the set-up, the guy showing up in the bar, the little bit of tension there with the poker players. But I think you jumped too quickly to the time travel thing. Once you cut to the guys fixing the white caddie, if you hadn't included in the description it was about a mechanic and time travel I don't think it would have been clear exactly what's going on. Also, some of the dialogue is hard to make out.
That aside, I'm a fan of Guntown and this is the same location, yes? It has an authentic old-west feel, the costumes are pretty much spot-on and your actors do a good job (though again, some of the dialogue is a strain to hear). Keeping in mind this was conceived and shot in 24 hours, I think you've got something here which could be fleshed out to feature length. Expand the set-up, and drop some hints here and there referring to time travel before actually showing something so modern in the old west setting, and I think you could really have something here.
My two cents. Take 'em for what their worth, which is about two cents.
