I need some advise on a stalling problem I have with my 50 diesel.It has the Buda 273 with the American bosch injection pump.I've owned the tractor for 25 years and only use it for pulling 6-8 times a season.It has always had a problem starting if I get it up to normal operating temp,shut it down and try to restart it in a minute or 2.It will crank real good but won't fire as if it isn't getting any fuel,plus there will be no smoke coming from the exhaust stack.If I coast start it,it will start up,I assume because it cranks the engine over faster.If I let it sit for 10 minutes and cool,it will fire right up with the starter.I have turned the pump up some to get max hp from it.If I turn it up past the max hp point a few turns,it will start right up with the starter even if warm,then I turn it back to pull.
Now this year it shut down on it's own after idling on an 80 degree day for about 20 minutes while I was warming it up to pull.I know it never got above 160 degrees.I had to get a pull to start it and after a few try's it sputtered and came to life.It never skipped,just kept trying to cut out a stall.I didn't have to bleed the injectors,it smoothed out on it's own after I ran it at half + throttle for about a minute.Then I pulled with it and it ran perfect.
Then today while waiting in line to pull my second class it began to cut out and would have stalled again but since I was sitting on it I throttled it up to keep it running.I made my pull with excellent power then shut it down.I restarted it ten minutes later for another pull and again it ran perfect.Nether the pump or injectors have been off the tractor since I've owned it and maybe never before that.All filters have been recently replaced.Since it seems to loose pump pressure at idle when warm,I've been thinking a pump and injector service may be in order but have put it off since it still makes 60 hp on a dyno.I'm hoping someone may have had a similar issue and can give me some advice on whether I need to spend some money on a pump/injector overhaul.If it would cure all these problems and maybe give me a few mores horses too I'm all for it.
