I'm really not intending to debate you. I'm make it my last input on the issue. The injector nozzle itself is measured in microns (one-millionth of a meter). It takes an imperceptible amount of stuff to screw it up. Without professional ultra-sound, etc, equip to clean it, I don't understand why you're so confident. Nevertheless, all the best with it.

This!

I agree here. It takes specialized tools to clean an injector. Sticking a needle into the nozzle (which is what some people are tempted to do to clean an injector) will surely have damaged it if that is what was done.

Having said that, I vote for the alternator binding and causing resistance.

The fuel has all been replaced.

It is possible that something is going on with the throttle/governor. I will look into it a bit more.

Yes the batteries were dead after the run. That's because when the key is off, there is no field current to the alternator so it doesn't produce any voltage. The other thing with the key off is the electric fuel pump doesn't work. My engine doesn't seem to have a mechanical lift pump.

Perhaps somewhere there is a mechanical pump in series or in parallel with the electric pump? Unless fuel will gravity flow from the tank I think you would need either a mechanical or electric lift pump?

If so, maybe they are interacting with each other. A drawing of how your fuel system is configured would be helpful.

I understand and appreciate your concern and I am not going to assume that the injector is good. I will, of course be wary of the injector and may in-fact end up replacing it. But I can assure you that I fully and carefully disassembled the injector, every part was cleaned and inspected under a microscope. Then each part was lubricated with light oil and reassembled. The injector on this engine is a rather simple mechanical affair. It is not like an auto injector with solenoid and extremely fine holes. It is a precisely machined pin which is held in the end cap hole by a spring. The fuel pressure is countered by the spring until the "pop off" pressure is reached. At that time, the pin retracts out of the hole in the end cap and the fuel escapes out of the hole.

Again, thank you for your assistance. I am appreciative all all comments and theories. Some ideas I had not thought of, some I had, and others I am reconsidering.

Keep'em coming!

Re: Partner shut off key on overnight run now engine won't run...

After years of electric assist fuel pump ,no surprise that sudden demand to go it alone,the mechanical pump gives it up. weak return spring fail or suck air when before was all right ,Cam lobe is worn (or cam following arm) and didn't matter before. Love a mystery, let us know.

+1

Alternator dragging enough to choke down engine at idle isn't realistic. Belt would slip, screech, or smoke.

A quick update:

It is not the alternator.
It is not the electric fuel pump.
It had no bubbles in the fuel.

I am most suspicious of the injector pump or injector so I have removed the injector pump. I have not inspected it yet. Hopefully I'll get to it tomorrow.

Is this a problem under load or present with no load? Black soot means unburnt fuel doesn't it?
