My best guess is that it is starving for fuel. As the load increases so does the demand for fuel. It is common for trash/rust to accumulate in the bottom of the fuel tank, the cut off valve, filter and the inlet to the carburetor. I am uncertain with the 801 but some of the tractors of that age had a screen at the inlet into the carb. Those screens cannot be seen as the are on the inside at the inlet fuel line. If the tractor was mine I would very carefully remove the fuel line at the carb and observe the amount of fuel coming to the carb from the fuel take with the cutoff valve fully open. The stream needs to be as large as a small drinking straw. Once you have the fuel line removed from the carb you can observe if there is another fitting between where the fuel line meets the carb and the carb housing itself. If unscrew that and pull it out and clean it. I cannot over emphasize that you must be careful in removing the fuel line from the carb because the nut that holds the tub to the carb will round off. Post your findings. I know a few other things to try but am out of time now.

My old Case has a screen in the tank....don't know about old Fords. Might be worth a look.

So far today I drained the tank got the screen out going to tractor supply tommorow to see if they have one.If they dont have one I will put in a inline filter.After I drained the tank I ran a magnet down in and around inside got alot of fragments of medal.How would a magnet work left down in the tank to get fragments I missed.

Most times you can just clean and reuse them

I don't see how it could hurt

The screen in the fuel tank is too coarse in mesh and too small in surface area to really work great. Here is what I do. I remove the screen from the old original gas tank unit and I locate a brass barbed fitting the will fit a small flexible fuel line that I buy by the ft at NAPA. I remove the screen from the old fitting and if necessary I bore the hole to where it will permit the barbed portion to slip fit. ( the shank of the barbed fitted is cut off from the threaded base and I only use the shank which I solder into the old original fitting that I removed from the fuel tank) Remember the rubber fuel line must not exceed the diameter of the threaded exit hole in the bottom of the fuel tank. I put enough the fuel line on the modified barbed original fitting that goes into the fuel tank to where I can fish the end out the fill hole in the gas tank. I then get a barbed inline fuel filter and insert it into the fuel line and drop everything into the gas tank. I now have created a replaceable filter that is inside the gas tank that has good filtration and a large filter area. This method eliminates the exit hole clogging issue in the bottom of the fuel tank getting clogged. Should you need to change the added filter in the future just use a wire with a bent hook and fish the filter out through the fill hole.

PS....you do need to verify if your 801 has a wire mesh filter inside the carb at the place where the fuel supply line attaches. It is not obvious that it is there on the tractors that use this method. The tractors that do use this also have one in the gas tank.

I wound up taking out the tank for cleaning. Put a length of chain in the tank and shook, then rinsed with clean gas a couple of times.

Without coating the tank it will rust again. You need to take precautions now to deal with the future rust to avoid having repeat problems. Put the filters in place. Have you fired the tractor to see if the problem still exists?

Put a couple of marbles or ball bearings in the tank. Doing so will loosen any remaining rust.
