I've never had to re-adjust one. The only problem that happens with the AARs
is that they get stuck. They either work or they don't.]]]

 

I have to respectfully disagree with you on this Jim. I agree on the stuck
or not stuck part, and I agree that if your AAR was never adjusted since new
that is it more than likely set just fine. But in the 40+ years these cars
have been around mechanics that don't know what our FI systems are all
about, the factory adjustment could have been changed at some point.
(probably a bad guess at a solution to a different problem) I'd bet there is
enough adjustment travel on our AAR's to where there is almost no AAR
function and it is closed off all the time - or too much air to where it
never really closes off when warm - and everything in between. I'd also bet
that in Dennis's case - if his AAR was wrongly set to where it let no air in
when cold - it would not cold idle well like he is seeing in his video.

The idle still needs to be set at operating temperature.  And it don't idle
right at operating temp because of this either just a little better.  I will
check this in the way you say Dave but it looks like some other things need
to be address as well.  This is why I like this list.  Good info to get from
all.  Now if I can find just as good of a place for the Digifant II FI on my
son's 88 Golf.
