high idle, 3000rpm idle Options

[slotty008]

Hi guys ,
I just hope that someone could help us with the idle of my '75 2.0. I have the car for almost 7 years now and idle was always a little bit too high. We have been trying to correct this but it got worse instead of better. We changed the distributor to a 123 ignition, we changed all the vacuumlines, the AAR has been cleaned out and the idle screw is completely closed.
The car starts at 1600rpm when cold and once it is warm it goes to 3000rpm and the idle stays there. The car pulls very well , a lot better better than when I just had it.

I'm going to say you have:

a. a vacuum line disconnected or routed incorrectly, and/or

b. the wrong curve picked for the 123 dizzy -- when I installed mine I had to use one with vacuum retard, not advance, option off the throttle body -- otherwise I ended up with a situation like yours, and/or

c. your timing is just too far advanced

(IMG:style_emoticons/default/agree.gif) but the idle screw hard and fast also (IMG:style_emoticons/default/sad.gif) another red flag with a false air idle like that it has to be one of the larger hoses ..thinking AAR also.
