Jay,

The trick is to gently pry the clip away from the wheel -- doesn't take a lot of force.  Look closely at the big watch spring in the center and you'll be able to tell which way to turn the wheel to tighten the spring.  I don't have mine in front of me but I think you turn the wheel clockwise to tighten the spring -- be careful about doing exactly what I say since I have been known to say something completely backward from what I did.  Be sure to count the notches as you turn the wheel so you can put it back if the adjustment doesn't work.

<< Last night I'm looking at my old (spare) AFC and trying to figure out how
to adjust the spring before opening up  the new one this is in my '85
Westy.  I want to lean it a few notches.  It looks like there is a clip
(looks like  paper clip size wire) that is screwed down and retaining the
large black gear.  I want to turn this gear clockwise?  If I remove the
clip, how does this gear turn?  I wasn't able to get the screw loose that
holds the clip down.  Does the gear lift and turn or what?  Is clockwise
leaner for sure?  I only want to go 3 or 4 notches and try it with my
voltemeter on the O2 sensor output.
