Kioti CK30
Looking for a little help from the pack. I am having a fuel delivery problem with my CK30, I think. Was moving snow a couple of days ago, for about an hour. A friend stopped by, so I shut 'er down for a few minutes, then the wife showed and so had to move the beast out of the driveway. Moved about twenty feet pushing with the rear blade and it just stopped. No joy on the restart. No smoke, no go. Fuel in the filter assembly looked good, clear. Popped of the lines, good fuel. Finally messed with the lever on the top, front of the injector unit, which I believe is the manual fuel cut off? Got it to run briefly twice, but would die quickly, especially if I tried to give it a little more juice. Third time it ran it accerated right up to the stops and I had to manually kill it with the lever(fuel cut off).

I let it sit for awhile then went back to try again. Got it to start after many cranks but could only move it about twenty feet at idle speed. As soon as I gave it a tiny bit of throttle, it died again without restarting. I called a nearby dealer(this is a Saturday) and talked to a knowledgeable guy, but not their senior tech. He suggested jelled fuel or ice from water contamination. I do use Power Service in the white bottle for anti-jelling and keep it plugged in with a block heater. Fuel in the filter and in the lines looked good. Tried bleeding air half a dozen times. I finally covered it with a tarp and put a small space heater on the injector side of the engine. Three hours later I got it running one more time, but wanted to die if any amount of throttle was given. Crept it into the garage at idle and put 'er to bed for the night in a heated environment.

This morning go try again, she's been inside in 55-60* environment all night and block heater on, it starts immediately but races to the stops again. I shut it done as soon as I could and let it sit. Did not have an oppurtunity to call dealer today, but will do so tomorrow.

So what do you all think here? Do I have ice somewhere in the injector unit? The electric solenoid fuel cut off does click nicely when key is turned, so that appears to function. Sorry to be long winded, just trying to give as much info as possible. Any other areas I should look at?

That is an interesting problem and well beyond my diesel skills but I'll be interested to see what some of our more experienced hands have to say. :confused: It seems odd to think that freezing had anything to do with it given that the engine and injectors were presumably at operating temperature when you first stopped it and could not have frozen in the limited time you stopped. Likewise, it seems odd that while it won't run properly it can race which seems to argue against a fuel blockage.

Rick, where are you?

I think you're headed for a dealer;sounds like the injector "rack" is the problem. The rack is located in the injector pump and controls the amount of fuel delivered to the injectors;sounds like yours' is sticking or perhaps the spring is broken/hung up, or the rack itself may be damaged:eek:

IT; yeah I doubt the ice thing too since the tractor was at operating temp for awhile prior to the problem. Plus the overnight in the garage did not cure the problem.

Patches; injector rack? You're just full of good news....:( Yikes! Thats definitely out of my realm of experience/ability to handle. If damaged, how does that normally happen? I certainly hope it is nothing I could have done through negligence or recklessness. I understand about springs hanging up or breaking.

Will see what the dealer has to say this morn. My problem here is I've moved and no longer within the working radius of my original dealer who provided excellent service. There is a Kioti dealer about 35 miles away who I called on Saturday. Will call my original guy first for ideas since I know him.......and pray for a "easy" fix. If not, looks like I'm cultivating a new relationship.

Thanks for the replies.

williek; Nothing you did caused it and you could have done nothing to prevent it from happening,if in fact it is the rack. Just one of those things:( Any chance the unit is still warranteed:D

Yup, still under warrantee. It's a small consolation though with all this mess left over from that last Nor'easter. Called my original dealer and spoke to one of the techs I used to deal with. He came to the same conclusion regarding the rack as the possible culprit. He stated they've seen a few go bad in the newer DK line but none on the CK thus far. That's my luck to get the one in a million........

Spoke to the nearby dealership, but the Kioti tech was out. The gent I spoke with wanted me to eliminate fuel issues first so I treated with Diesel 911 and new fuel filter. Still no joy. So I guess my 30 is off to the tractor hospital. :(

In another post titled " My new CK20hst loses power / rpm . sounds something like your problem and it ended up being something blocking the line from the tank . Hope this helps . Please post back on the FIX .

But the runaway rpm's point toward the rack.

I am on my way to Vegas with my bet......
Someone needs a new injector pump.
Anyone want to go double or nothing?

Willie: Is it still under warranty?
