Working on a 1630 New Holland. Bought it not running and rebuilt the engine. Had a rod bearing getting ready to spin a had to get the crank turned. Got it back
together but, it doesn"t run as it should. Runs like it"s starving for fuel. Has good fuel quantity at injection pump and fuel is getting to the injectors. Can get
it running but, it doesn"t throttle up nearly as fast as it should. Sounds like a diesel when it"s running out of fuel. If it was a gas engine, I"d say it was
timed too slow. I"m not familiar with injection pumps enough to know if it is just tired out or out of adjustment. There is a stem coming out of it that has a
safety wire attached to it so it can"t be rotated. I"m thinking that it is a fine tuning point and shouldn"t be adjusted. Any help would be appreciated. thank you,

If you removed the injector pump you need to spill time it as the timing is set with shims where the pump mounts to the engine.

That engine has a PFR injection pump that uses a separate engine cam to operate the pump roller tappets. Shims are used between pump/block joint to change timing, and are usually to be left alone. REMOVING shims will ADVANCE timing, ADDING will RETARD timing. Does engine smoke at all under heavy acceleration? NO smoke/slow acceleration can be caused by worn pump plungers. Changing the max fuel setting on engine might help.

That engine also has 2 different size head gaskets available and you determine the proper gasket according to the piston height.

Could I pull the pump and remove a shim to try it and if it doesn't help, replace the shim and go to a different fix?

Isn't spill timing needed to insure the engine to pump timing is correct?

If the pump wasn't removed during the rebuild that is not your problem. If the pump was removed how did you determine how many shims to put back in.

Did not remove when rebuilding the engine. I don't know how long this machine had set before I got it so, would old fuel be a cause of my problem?

If you are unsure of the fuel just drain it and put in fresh fuel. Does the engine smoke and if so what color smoke are you getting?

I haven't been able to get the engine running and I did drain the fuel and replace. Would it matter that I put in home heating fuel.

Yes it does matter. Heating oil doesn't have any lubricating qualities which is needed to lubricate the pump and injectors. Your original post stated that you had it running but it didn't turn up as it should.

Heating oil would fire the same as diesel fuel; right???
It was running but, now I can't get it started.

Heating oil does not lubricate the moving parts in the pump and injectors which can cause them to stick. Heating oil is not a substitute for diesel fuel.

I'm going to replace the heating oil with diesel fuel but, I don't think it will solve my problem. I've run heating oil in a 1620 Ford, with the same engine, for a couple years.

When putting this engine back together, I was careful to align the marks on the ends of the crank, cam, and idler. Is there any other timing that I've missed? When I crank it over for 5-7 seconds it will start blowing a grayish smoke. Appears to me it's blowing unburnt fuel out.
