George,
I assume that adapting the electric AAV from the K-jet would involve tapping into the intake manifold at some place. Are you actually contemplating going this route? If so, I'd sure like to hear how you make out with it. I was just checking on the price of a new one of the D-jet type; $389 tends to give me a lot of thought. If used ones are as likely to be as faulty as you say, have you given any thought to installing some sort of valve after the AAV, be it electrically, thermostatically(?) or manually controlled ? Perhaps, route the hose through the firewall with a manual valve under the dash that you open when you start the car and close when the engine is warmed up?
Anyway, after I shifted the distributor -- I jumped a notch with the dizzy drive before I read your easier 90 degree solution -- and adjusted the timing to about 12 btdc, I got rid of the surging and fiddled with the idle adjustment screw a bit (which I found to be totally closed). Now it idles at 900 rpm with a clamp on the AAV hose and at 1500 with the clamp off. So, no doubt, a faulty valve. So, till I find a better solution I, drive the thing with the AAV blocked off.
