Finally the mud dried up enough to go get the tractor; it was 30 miles away. You guys were spot-on about the problem: The injection pump was gummed up. The new problem is how to remove it when I can't find the timing mark in the sight window.

Thanks for your help.
 

Glad you found the problem. The timing mark isn't difficult to see. You may have to blow/spray out the coffee grounds.
 
Some very rusty pumps I see in for repair timing line is impossible to see. Set the flywheel where it belongs, pump will have a 50/50 chance of being in time. LEAVE the drive shaft in the engine, then remove the pump. Look for a dot on the shaft tang end, it should align with the pump slot dot inside. Dots SHOULD align when going back together, if dots WERE NOT aligned, then put the pump back on after repair the same way. After pump is on, if you can see the pump timing marks in the opening, get them aligned with the correct flywheel mark. If you DON'T see the pump mark, turn engine ONE turn then set timing as needed. Pumps I repair have a better mark to see, even if rusty inside. If you remove the drive shaft, then the valve cover will have to come off to see that # 6 rockers are on overlap, which verifies # 1 is on compression.
