Hello Everyone
Hopefully someone can lead me in the correct direction here. I have what I believe to be a late 60's (S/N tag missing but it still has a generator rather than alternator) MF-135 diesel. My problem is that at low speeds, that is less than 1100-1300 RPM it seems to only run on 2 cylinders. Above that speed it purrs like a kitten with plenty of power. I use it mostly with a 6' finish mower to keep our 5+ acres mowed. The governor seems to respond to loads very well and other than this one small problem I'm more than happy with it's performance. I've loostened each injector line at the pump one at a time (yes I was careful, I'm used to working with high pressure systems) and pretty well narrowed it down to the rear cylinder. What do I need? New/rebuilt injectors or an injector pump overhaul? Also, after a period of extended idling (10-15+ minutes) it will very slowly decrease in speed and sometimes just quit. It always starts back up but seems to take a little bit of extra cranking to get it going. Cold, it starts almost instantly. Any help would be appreciated. Oh yeah, what would be a fair price for a set of rebuilt injectors if I have to go that route? Any suggestions as to where to get them?

how much pressure is at the injector.. injector pump may not have enough pressure on one cylinder to fully close the injector after fuel injected, thus continually spraying fuel in line with the other two cylinders. pump probably needs rebuilding too much slop in it till it gets would up. also check to gear that runs the injector pump, may be wore or loose

I purchased restored 35 yesterday it seems to have a similar problem,it runs on two contiuously with a black smoke at low rpm. If you solved your problem I could sure use some help.

Mark,
If you swap the injectors around does the problem follow the injector or stay with the 3rd pot? The answer to this question will tell you if you have to rework/replace your injector(s) or you have to look at the valves in the head.It does sound like the injector is leaking thats why at idle the engine sometimes cuts out because it becomes flooded.

Hope this will help.
