I put on reman carb,reman mag,new plugs,steel core wires. Running out of ideas. Manifolds ever burn out internally? Have played with timing and carb adjustments a lot. Thanks in advance for any help.

Does it have any ethanol in it? I had an M this summer that was giving me trouble wasn't running right. I talked to a fellow who has worked on farmalls for years and he told me to get 93 octane without ethanol. Tractor has run fine since changeing gas. Just an idea. [Reply]  [No Email]

I own a 1940 Farmall M, and a 1940 Farmall H. Both of those tractors run excellent on E-85. [Reply]  [No Email]

Has it been run enough since the overhaul to seat the rings? It should still run okay at 100 lbs, so that isn't the problem, but it just seemed low for a rebuilt motor. [Reply]  [No Email]

Get engine warmed up, if you can. 2. Top carb screw, the outward-facing idle speed screw @ 450 rpm. 3. Middle screw, the forward-facing screw, the idle mixture screw; start @ 1 to 1 1/2 turns open. (Turns clockwise for rich.) 4. Main fuel adjusting screw, the bottom angled-backwards screw; start @ 2 1/2 to 3 turns open. (Turns clockwise for lean.) 5. Points set @ 0.020", or a match-book-cover"s thickness slid back and forth. 6. Timing, dunno. 7. My old notes say valves @ 0.017" warm, 0.020" cold. You ought to get a manual, there"s a lot on tuning, these are just what I use as the start positions [Reply]  [No Email]

That remanufactured SHOULD have already been adjusted to factory initial settings, and you should not have any need to tinker with it. 9 times out of 10, an H that runs poorly is suffering from insufficient spark advance.

That was all that my H needed. I would check valve adjustments one more time as well... [Reply]  [No Email]

Manifold or gasket could cause problems too. Im sure someone else will chime in...I think you can spray WD40 on the manifold and around the gaskets and if the engine smooths out, you know you have a leak and are sucking air. [Reply]  [No Email]
