I would like to raise my idle just a tad, it seems a bit too low, sometimes in heavy work traffic, you know, 1 block 3 minutes, it starts to idle a bit lower, and starts to shake a bit, All i need to do to stop this shake, is run it through 2nd and 3rd, then is ok for ten minutes, Thinkning the idle is just a bit too low for getting stuck in that kind of edit,
Thank you!
Peter

 

As you look at the injector pump from front , on left side between engine and pump id the idle screw, loosen the jamb nut and screw it to the desired idle. PS the nuts kinda hard get to, use a punch to tap it loose.
