d427 Posted April 15, 2013 Share Posted April 15, 2013 Hey guys. Got truck back with new kinpins and wheels powdercoated. Also, I cut down stack and painted flat black.I have been doing all fluid changes and general mechanical myself but am wondering how to bring up my idle speed a little. It is idling at about 500-550 and shakes truck real bad as you can imagine. My question is about the fuel pedal. Do I have to adjust it on the pump or can I fiddle with pedal assembly. Any advise would be greatly appreciated. Thanks! Will post pics when I get a chance Quote Link to comment https://www.bigmacktrucks.com/topic/30827-b-model-idle-speed/ Share on other sites More sharing options...
Superdog Posted April 15, 2013 Share Posted April 15, 2013 doesn't your hand throttle work? Quote Link to comment https://www.bigmacktrucks.com/topic/30827-b-model-idle-speed/#findComment-178127 Share on other sites More sharing options...
farmer52 Posted April 15, 2013 Share Posted April 15, 2013 As Mike states...use the hand throttle to bring up the low idle. Otherwise, adjust the low idle speed at the pump.

d427 Posted April 16, 2013 Author Share Posted April 16, 2013 Thanks guys. When weather clears I will try the hand throttle. I kinda forgot about that lever. My mechanic adjusted throttle linkage and pedal has nice feel to it but want it to idle just a little higher. Thanks for the advice!

Maddog13407 Posted April 16, 2013 Share Posted April 16, 2013 throttle pedal has nothing to do with the idle speed and you should only adjust that so it backs off all the way and goes down til it hits the hammer bolt in the floor.you have to adjust it on the pump. suprised Dennis never did that...

d427 Posted April 16, 2013 Author Share Posted April 16, 2013 The truck did idle a little higher when I got it but the pedal was sloppy and would stick so while it was in for kingpins and brakes I mentioned it and they adjusted linkage and it is great but now idles low. Lots of stuff unhooked and wires cut when I got truck so just trying to figure everything out.
