  • Maybe I don't need a major?
  • Warmed up the 1945 2N to do a second compression test. 1st cylinder was 80psi, 2nd was 75psi, 3rd was 65psi and 4th was 75psi. I wet checked the 3rd cylinder and it was 70psi. The numbers look better, maybe not great but the tractor is a 1945. If the compression on the 3rd cylinder increased with oil, would that mean the rings are a little worn? The tractor still has hesitation in throttling up, some small back firing if you would call it that. Have not put it to a test in the field because its 34 degrees here in South Dakota. What do you guys think? Bob E

  • Backfiring sounds more like a carb coil or point gap issue more so then compression issue.

  • Yep, that is the tractor will run numbers. The other numbers you post did not sound like the tractor should run. You should take it for a try out soon a your weather is better.

  • May not need a major but once you get into it to replace pistons and rings mission creep will see it. How is your oil pressure? You may find you need new sleeves and before you know it you are doing a major.

  • I know a coil has been mentioned. A few years ago on my 8N with front mount distributor it would not run after it got warmed up good and would not restart until it cooled down. I tried adjusting carb and points with no improvement, I put on a new coil and that solved the problem. A few months ago someone posted a stalling problem on their tractor, I suggested they check out the coil, another posted that coils very seldom if ever go bad and that you would be wasting money replacing things that don't need to be replaced. I have replaced this coil because of the same problem a couple years ago. These new coils may not be of the highest quality. I also replaced the gasket. I really enjoy my tractors and like to hear what others have done to address their problems. Thanks Bob E
