Scotty: When I first got my Super A, it hadn't been used much in some time. First few days it worked fine, however I was using it on rough hard ground and looking back that would have caused a lot of gas movement within the tank. After about a week I could only get it to work a short while, and it was as if tractor was out of gas. First time I thought it was out of gas, thought to myself this SA is a lot harder on gas than my 130. Poured couple gallons in and by that time it fired up, but only ran a short while and stopped again. This time I put a wood dowel in tank and much to my surprise it was close to full, much more than the two gallons I added.

Over the next couple days I had the carb off 6-8 times cleanig it, and all of a sudden once there was no gas flow from tank. I removed the sediment bowl base, and the stem was full of flakey rust. All I can think is those rust flakes must have been moving constantly. Yes, each time the tractor stopped, there was that air bubble in top of sediment bowl. Could be air came back from carb, I'm not sure. Tractor did have a cork gasket between bowl and base. Did it suck air through the cork gasket, yet not leak, I'm not sure I buy that either.

I do know that once I got the tank cleaned of all that rust, plus the bowl stem clean, my problem went away, and that was many years ago. I do know those rust flakes in the sediment bowl stem and shutoff did not come out with 100 psi of air. I dug them out wife one of my wife's darning needles. I think before Muley says, "nothing in stem", he best do a bit more investigating. The air bubble is created by a vacume, however small, and that brings me right back to the graviety question. Liquids do run down hill, at least until they meet a blockage.
