A little over a month ago, I bought an old style Ford 4000, 4 cylinder, diesel tractor. It's in the vintage of 1962 to 1964. I've done a bunch of minor repairs on it - replaced the fuel gauge, replaced the headlight switch, rewired the headlights, changed all of the fluids in the tractor, replaced the fuel filter, cleaned the air cleaner, cleaned the rocker arm breather, adjusted the friction washer on the throttle bell crank, etc.
I ran it hard for about two hours today bush hogging some tall weeds/grass in a moderately hilly area. It ran very well, except, in the last 1/2 hour or so, I had to keep opening the throttle a little at a time to maintain the engine speed at 1800 RPM. Finally, I had the throttle all the way open, and the engine wouldn't rev up beyond 1500 RPM.
I quit bush hogging and went home. Now, with the tractor parked, in neutral, with the PTO disengaged, the engine won't run above 1500 RPM. I checked the throttle linkage to insure that it was opening the actuator on the injector pump all the way, and it is.
Any ideas what I should check next?
Thanks for any advice.
