Kioti LB1914 Hard To Start When Cold

[1 ALC]

My Kioti tractor is hard to crank when cold, it has 460 hrs on it. I let the glow plug light go out, then it spins easy (even with out the compression release), it will almost start, but will choke out and flood. It usually take 30 minutes to get it to run whne its below 50 degrees.

The man I bought it from kept it inside a heated shop, but he said it was cold natured when he had it too.

I'm afraid to use ether , since it has glow plugs. It has a throttle stop, my buddy (whom I bought it from) suggested trying to pull the throttle stop partly out to reduce the flow of fuel. ??

Could the glow plugs be worn out?

-Thanks,

Never use either on a rig with glow plugs or grid heaters, it can set of an explosion in the wrong place. A diesel doesn't flood in the gasser sense, I wouldn't be concerned about that, and would even suggest half throttle when starting. It's just too cold or your glow plugs aren't all working, they do wear out quite often. I have a small Kubota that is just as cold blooded, it takes 30 seconds of glow plug even in the summer and a couple minutes in the winter. Unless it's totally warmed up it will need the glow plugs every time you start it. Been that way since new. Smaller engines seem to need more preheat. Unless some of your plugs aren't working my feeling is you just need to learn the quirks of your new tractor. You may have to cycle the glow plugs two or more times to get it warm enough. Glow plugs are easy to check, just feel if they are getting warm from the outside, no need to even remove them.

Try this. On my Massey, I move the key to the left to activate the glow plugs. I put it into the vertical or off position and pause a few seconds. Then, I put it in the on position and pause a few seconds. Then I crank on it and it fires right up. If I just rapidly switch it over, the fuel shut off selenoid will not move to the on position. Even in the summer, I have to give the selenoid time to move.



My next step would be to add a block heater. Another trick is to put a quartz work light close to the injection pump for awhile. Another trick is push hot air into the intake with a hairdryer or a heatgun.



Take a big diesel like my 504 Case without any help, you have to know the tricks when it gets down in the single digits. Course, I can use either on that.

Hmm, I reread your post. Throttle stop? So no selenoid then. Is the stop correctly adjusted?

I borrowed my neighbor's Kioti recently and it too is very reluctant to start cold. Half throttle helps as the governor does not step up the fuel much when it is cold and stiff. I glow pluged, cranked until the rpm drops from glow plugs cooling off and repeat the glow crank cycle. Each time a little more heat is retained in the prechamber and it eventually starts. It took me 2 or 3 tries at 35 - 38 degrees, so I imagine a lot more if colder. Need a good battery!



Any small diesel is a a great disadvantage cold starting. As displacement is smaller there is more surface to volume ratio in the chamber and the compression heat is quenched more effectively.

My 40hp Massey has one of those 3 cylinder Iseki engines. Once I learned how to deal with the selenoid, it fires right up. If it's down below say 20-25 degrees, I will plug it in for an hour or so if I have time and plan on using it. I don't have to plug it in. I just feel over time, it may extend the engine life by doing so.



Big diesel's are not so great once that oil gets cold. They can get so stiff, they won't even turn over.
