[Farmall] Farmall Model H - Cuts out after 45 min to an hour

[Mike Sloane]

If you have replaced the magneto with one having a known good coil, then 
the only thing I can think of is a blocked fuel cap vent that is 
creating a vacuum in the tank. If you still have the old (original 
almost flat) gas cap, I suggest you replace it with the newer (black 
cylindrical) cap that you can get for free from Navistar. You need to 
see if there is good fuel flow when it cuts out - if there is, that 
eliminates the vacuum problem and the problem is likely the coil or 
condenser.
