Another issue that I have with this machine that i would like to get a handle on before I mess with the timing is an issue with cold starting. I should probably give little history on the machine first. This machine has about 4000 hours on it. I bought it as somewhat of a "project". The machine had been sitting for a about a year because, according to the previous owner, the injector pump went out. They removed the pump and took it in for rebuild. Subsequently, the rebuild shop "misplaced" the pump and ended up replacing it with a new (not rebuilt) unit. The previous owner never installed the pump and decided to get rid of the machine. That's where I come in. I purchased the unit and had the local Case dealer install the pump. They installed it, got it running and did a systems check. They recommended some injector cleaner and went on their way. Another part of the story is that the previous owner had bypassed the control unit and the ignition switch. They ran a hot wire to the fuel solenoid and left the other (I think it has to do with cold starting) wire on the pump disconnected. I have since replaced the control unit a corrected the wiring issues.
The current issue is that the machine is incredibly difficult to start cold. Once it starts, it will idle weakly and the throttle has no effect on the engine speed. It will not throttle up. It will do this for about five plus minutes. Eventually, if I turn it off, recycle the heating element and start it, will power up and run fine.
I have done the following to the unit:
Replaced the injectors
Replaced the fuel filter
Drained the tank and put in fresh fuel
Changed the oil and filter
Replaced the air cleaner
Checked the turbo (shaft is tight, spins freely and not wet oil residue)
Thoughts/suggestions
Thanks
