Got the lock the lock ring off the fuel screw (amazing what u can do with a Dremel) Screwed the the screw back in smokes but not alot. The only thing is I cant get the idle to come down to a respectable grumble. The idle screw is backed all the way out. Pleasee help.

 

You have to compromise-back the fuel screw out a turn to get idle down!

 

Is the idle screw touching the throttle arm? You sometimes have to do a little grinding because the arm hits the pump. The linkage may also be stopping the arm before it hits the screw.

 

My cruise control cable is like that. With the cable on, the throttle won`t return all the way. I`ve been too busy to really look into it so I just took off the clip and popped the cable off for now, can`t use cruise around here anyhow.

 

That idle screw is a fun one ain't it! I had to put a little piece of wire in that hole in the end and then run the lock nut all the way against the wire to turn it. Haven't figured out what do to if I ever have to go the other way!

 

I used 2 oring picks and a screw driver to help turn that bugger idle screw

 

What would happen if you simply re-indexed the linkage on the throttle shaft? I know you could reduce idle speed this way, and it would get you back into the area where you could adjust it by turning the low idle screw, instead of grinding off the linkage. What I'm not sure of is what effects, if any it would have on the high end. Any thoughts?

I did the same thing with the picks and the little hole at the end of the idle screw wow wat a pain that was! Yes wanna diesel the idle screw is backed out all the way. The 10mm bolt on top is the throttle index I tried to adj it but it made no difference . Its to cold out to day to fool around with it and Iam not driving the truck anyway so thank you all for the help John
