High idle?
Hi all,
Maybe cause I'm new here I should have posted this here first - no replies in the 84 section.
I’ve recently started using my 84 as a DD. It’s idle is running a bit fast 900 vs. 750 per the sticker. I can’t go lower as tip of the screw is no longer touching the linkage piece it should be sitting on. I’ve checked the timing (advance vacuum plugged) which is per sticker at 5 degrees, I have seen a couple posts here say different though. No vac leaks that I can find. It runs very good but is getting low mpg (under 20), and I have been pretty light on the pedal. With all the vac lines and attachments to the carb (stock Aisin) I’m kinda new to these trucks and wondering where to look next.
FWIW, the truck was worked on (timing chain & cover, valve adjust, fuel filter) just before I got it by a guy who most everyone says is questionable.
Thank you,
L
