fuel smoke and skip

[downriver]

have a LB1914 Kioti four wheel drive when starting it smokes real bad and skips the smoke is fuel after a few minutes of running it runs fine and doesn't smoke when under a load or about 2200 rpm not under a load it starts smoking again and will miss and skip if its under a load at lower rpms it does fine like lugging in 5th or 6th gear when I crack the injectors two and three are good number one doesn't change when I crack it I am suspecting that when I put in new rings and bearings that either a ring got broke or put in upside down after the engine comes up to operating temperature it seems to do some better I have worked on bigger diesels and never had problems like this

Why dont u suspect the injector.?? & why dont u use punchuations.?? a simple "period" would make that much easier to read & answer.
Have u removed the inj. lines & compared the squirts from the pump.. maybe the pump is bad??
U could remove the "bad cylinder" injector & swap it w/ another & do the check again..
I sure hope its something simple & u dont have to rip the motor down again.. Good luck.

swap #1 injector with one of the others and see if the miss follows #1 injector

I have swapped out the number one injector to other cylinders am getting the same thing on number one cylinder.as the engine warms it gets less smoke and skipping below 2000 rpm.I now suspect a ring problem in the number one cylinder,can pull the head and the oil pan and check it ,was hoping for something simple but it doesn't look like its going to be. thanks for help

Time to do a compression test before you jump into this any further. If that comes up with low compression then do a leakdown test. This will pin point the problem area not just tell you there is a problem.

thanks for the advice.will do a compression check first
