Thanks. I am getting ready to temporarily hook up an electric fuel pump to see if it helps.
As far as cleaning the tank, I just did that recently and put in a new shut off valve. This is an old project tractor that I built a while back. It has the 1x9 gas tank.
I'll try the pump first and if that doesn't do the job then I will look at the tank again.
This all started kind of weird. I've been running this tractor for a good while with no issues. Then yesterday it started missing and I had to use the choke to get it back to the shop. This morning it started up and ran great for about a half hour or so and it started acting up again. While I had the carb off to clean it I turned the engine over (a lot) and didn't get one drop of gas.
