It' kind of hard to guess from here. That being said, a metering valve isn't going to get stuck just because it gets closed quickly.

My first thought is - the tractor was starving for fuel, had air or water in it, etc. - revved up, broke/siezed inside, and it quit. So, first thing to do is look inside and make sure it's all turning inside. If it's broke, a pump shop will raise their repair quote substantially.

Now, if the tractor had been sitting a long time, you started it, it took off and then shut down. Then it's quite possible the metering-valve is simply sticking and is now stuck in "off" position. You can't go by what the lever is doing on the outside. You've got to pull the top cover off and look inside. Download a free CAV DPA manual, it will help. Just do a Web-search for CAV DPA British taxi. Same basic pump and that full manual has been on the Net for years in a big PDF file.

I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga ...
