Any one here running a 92-93 6.5TD with a turned up mechanical injection pump? If so, did it affect your idol at all? I turned mine up a bit more earlier and its idoling at 1000 rpm instead of its usual 800

i adjusted it in the hole through the top, there was a small spring in the hole that i had to take out. its only turned a little over an 1/8th of a turn

Idle or fuel rate ? AFAIK knew the fuel rate was done through the side but that is only from the banks manaul. I have never done it.

no the spring was down inside the hole. it was kinda sitting in there at an angle, im not sure what its for but i put it back in like i found it

that may be what i need to do. when i took out the allen head on the back of the pump i measured the distance it was sticking out but maybe i didnt get it right? i will check it tomorrow and see if that helps. thanks

There is NO SPRING in the any of the holes in the above pictures.
It may be too late, but I think the small spring fell out of the 'slide pin hole'.

The main fuel rate can be adjusted in either fashion in post #3. You are turning the same screw. It's a PITA to use the triangle cover with the IP on the engine. The top cover carries more risk of F'ing things up doing it that way....however...

It is merely a guess on my part as to where the mystery spring came from.
I do know that almost every time I fiddle with the pin in a DB2, that damn spring falls out and I have to dig it out of the IP somewhere.
