I agree with 80 psi compression is low. Check your plug wires and also the condition of your distributor cap. Also check your points, they should not be burnt or corroded and set to the proper gap. Another thing that you could check is your valve to rocker arm clearances. They do wear and need to be adjusted over time and often overlooked. For what its worth, I had an M that I could not get to run right no matter what I did. It turned out to have a cracked head and a bad head gasket. After fixing it, it starts and runs perfect. M's where bad about developing cracked heads. Funny thing about mine was, very little water would disappear from cooling system. Non the less though, there would be a few drops of antifreeze in the bottom of oil pan. To check that on yours, just let the tractor sit for a few days and then loosen the oil drain plug just to the point that it will drip (don't take it out) and if antifreeze drips out you likely have a cracked head or bad head gasket. This creates compression problems, and moisture in the combustion chamber fouls the spark plugs.
