Oil & Fuel Ford 1210 injector pump

[tree grower]

My 1210 has 2300 hours and has provided flawless performance for 40 yrs. I just filled the fuel tank with the engine running, drove it 50 ft, and it bogged down but did not die immediately. Engine died and I could restart it, but it will not respond to the throttle. Can restart repeatedly, but no throttle response, then dies---repeat several times. Could find nothing wrong with fuel supply and cleaned out the air filter but no improvement. I cracked the bleeder valve and observed a ring of tiny air bubbles. Playing with the valve (unscrew a little, screw in a little, etc) will keep the engine running poorly, but the air bubbles never disappear. Does my injector pump need a rebuild ? If not what could be the problem.

Sounds like you stirred up some junk in the tank that was immediately picked up by the intake tube. I would change the filter, and if it improves, consider cleaning out the tank.

If you are getting air bubbles, it is getting in somewhere along the fuel line, filter or valve

Removed sediment bulb, cleaned out thoroughly, blew out supply line, bled bleeder screw and all three lines. Charged battery overnight, tractor started perfectly this am. Let it idle for 10 min while putting all tools away, throttled up to work, and it quit. It will start and quit, start and quit. Fuel line runs a full stream. Opinions requested.

The only thing I didn't try was new fuel. What I had on hand was several months old. I drained the tank, added new fuel, and it starts and runs fine
