hoodeleydoo posted a topic in IH Truckshi guys, I think im going to try to adjust my fleetstar idle. I have fresh fuel in it and have been using some fuel treatment cleaner (Lucas). its still too low. I think an additional 100 or 200 rpm would be just great - it would take the shakes out of the cab (so much I can see out the mirrors) as well as help with the shifting. I thought about limiting it with the pedal travel but thats not the proper way. so there is a tool to do it while running or you can do it by small adjustment when off then start er up and see. i dont have the tool but pretty sure I can make one. anyone have any advice or experience using the tool or not? any advice on any idle adjustments? I also heard that possible injector pump pressure adjustment may help but i'm not too keen on that. The engine runs out just great so I dont think there is an injector or injector pump/pressure issue. Thanks!!
