3cyl Diesel Not 'Warming Up'

[Dennis Mohn]

I see black smoke in your video. I would check to be absoultly certain the engine was getting all the air it needs first. Does this unit have an emergency shut down, is it turboed ? After I checked the air system I think I would check the injectors for spray pattern and pop off pressure. A fuel problem I would expect to see white smoke and smell unburned fuel.

Those that have not done so watch the video on post #32.
One poster mentioned a decompressor rod that runs through that area, something is going on in that area.
An engine manual needs to be located and that figured out and taken care of.

I doubt it is injector related.You have most likely a problem with the governor in the Injection pump.
On another note, check your fuel and air filter for being plugged.

I've had a Kioti for nearly 30 years in the cold Northern Rockies, and I've avoided problems by sticking with a few "must follow" rules:
1. Use only #1 diesel
2. Always plug in, even in summer. I have a lower radiator hose heater and 2 "patch" oil pan heaters.
3. Add a couple ounces of Power Service with each filling of fuel and Seafoam every 4 fillings
4. Leave a battery tender on between uses to insure full starting amperage
5. One full minute on the glow plugs

I've had my share of problems, but not with starting, unless I don't follow every bit of the above protocol.

This is what I believe the problem was. Over torquing the valve cover could change the decompression rod adjustment enough to cause a misfire. The PDF is from the parts diagram.

Sounds like it is only running on one cylinder. Could try bleeding injector lines and be sure you are using winter fuel and filter is not restricted

I did, it does move the throttle plate.
Mechanical knob shut off that has a linkage that connects to the same plate as the throttle linkage.

I have to keep the throttle up to keep it idling... Another detail to consider. But you can't really tell the throttle is up, but without it raised it runs for less than 30 seconds.

Also, there is no load whatsoever, clutch pedal is locked down, it does not continue to run for as long if clutch pedal is released.

Thank you

If it has glow plugs, it might need checking to see if they are all heating up. My old B1700 had a tough time starting, and only fired on 1 cylinder till warm. Removed the glow plugs and found them caked in carbon. Cleaned them up real good, reinstalled, everything fixed. Most diesels will pick up the other cylinders after a short run when the engine gets warm, but this doesn't sound like the case here. Next is the injectors which can be cleaned up by a diesel shop. After that, a kinked line, a leaking fitting, and maybe the pump, which can be rebuilt by a reputable diesel shop as well. Good Luck!!

Lots of good information. I filled my tank with nu 1 winter blend, smoked and ran rough, drained tank, changed filter. Cured problem, Gasoline was in the tank. talked to the manager he checked the tank and put it out of service until cleaned. First time I ever had someone react positively so fast.

 

[Dennis Mohn]

How much gasoline was in that tank??

Not sure on either tank. Mine was enough to cause problem. Showed the drained fuel to dealer thinking about damage to injectors or ?. For no longer than I ran it no problem. Has another hundred plus hours and is ok.
