This is my first post so I am sorry if it is a rehash.
The injection pump on my 1997 New Holland 1720 started to leak fuel into the crank case. I sent it in to be rebuilt and recently got it back from the shop. It is a Zexel piston style pump in the attached picture.
I was told that I could pull the pump and send it off and as long as I did not crank/move the tractor timing should not be off as long as I used the same thickness shim it should bolt back up and not have an issue.
That has not turned out to be the case. It is sputtering and blowing a lot of black smoke and will run away so that it will not shut off with the key and has to be starved of fuel to shut off. I have a Service manual on order and am hoping that it will have the timing procedure.
Any pointers I can get would be greatly appreciated.
Thanks in advance of any help I can get. Again, sorry if this has been asked.
