CK30 cold start

[CanuckGT]

Ok.up here in Canada its starting to cool off (30F) so I noticed lately when cold starting my tractor that it seems like it fires on 2 cylinders then fires speratically on the third until it fires normally on 3...if this makes sense,its like the 3rd cyl is firing every 3rd revolution then eventually catches up and runs normal,like clang...clang..clang....then rattle,ratttle,rattle normally....god I need a sound clip here...lol.

Is this normal,or maybe injectors are dirty or????

Thanks

Sounds like it's trying for "Oh, Canada."

Cycle the glow plugs 3 times. Up in the Great White North you should think about a block heater too.

On my CK30hst at 30'F, it starts fine with just one cycle of the glow plugs. No chatter and firing on all three cylinders. Not until 20', or lower, do I need two cycles. I wonder if one of your glow plugs isn't working.
Maybe try MotorSeven's suggestion and cycle the glow plugs again and see if still does the same on a start. If it does, you may have one bad glow plug.

Thanks for the replies, I will try cycling them a few times next time I use it.

If it is a bad glow plug,how hard is it to change yourself?

Thanks

OK, ran the tractor this afternoon,cycled glow plugs 3 times and still seems like it fires on 2 cylinders,the other bangs a few times before smoothing out and rattles with the others...not sure what to think...

I think Victor is right, you have an issue in the glow plug circuit of the plugs themselves.

There is a chance that you have one bad/dirty injector dumping in to much fuel but I think it would take much longer for that cylinder to fire smooth with the others. With three cycles of the glow plugs, all cylinders should be running smooth. Even at 0'F and two cycles of the plugs, mine clangs for @ five seconds and then hits on all three. I'd check the current going to each plug and then the plugs themselves. It's also the easier of the two to check.

Once that happened sort of in my ck30hst about 4 yrs ago, hard to start, unusual. I added a good amount of the white bottle Power Service to the fuel, it cleared it up pretty fast.

It is easy to check your glow plugs without removing them. Disconnect the current circuit off each plug and then just use an ohm-meter to check each plugs resistance. If you cant get a reading, the plug is a dud. A high resistance can mean the plug is on its' way out.
One lead to the connector on the plug, the other to earth.
