High Idle?
 

Hey guy's i need some information if possible, i just turned my fuel screw in about one and a half turns, and backed the idle screw all the way out and can't get my idle below 900 RPM's is there another adjustment that i am missing to get my idle down any help would be nice. My name is Roger by the way and i have gotten alot of great info off here, my truck by the way is a 92 d250 ext cab

Begle I like how you linked to a thread on 1stgen that links back here. :D

Maybe i was was miss understood my truck idles to high, by what i have read about re-idexing the pump it gives you more throttle swing and higher rpms i want to lower my idle, thanks, or maybe i read it wrong

Shorten the screw, try removing it all together, or grind some off the lever. Is your truck a stick or an auto? Some of the stick owners like there idle bumped up to around 850-900 to make it easier to start off with a trailer on hills.

Where do i need to grind on the lever, the screw is backed out and not even touching the lever at all, and it is an auto. i would like to get another turn out of the fuel screw but i can't because i can't get the idle down, thanks for the replie, i will look at it to see if it is hitting something that i can grind off.

Look for were the lever is contacting and grind there

RSwords i found what my problem was, i had adjusted my linkage to tight after i did my fuel pin mod thanks for the help, it had not seemed that tight because there was play in it, thanks for the help, i also have the full cummins manual if any body needs me to look up any specs for them, it is for the 85 12 valve cummins but it is the same motor we have in our trucks, thanks again for the help

Glad you got it straight!
