Okay! Yeah, took off cap and no plate movement at all. Guess there should be? Have electronic ignition in '73 dizzy but quite sure I didn't punch those screws too deep or through the wrong holes. Will commence breakdown!
I read somewhere sucking on the hose to the diaphragm of the distributor (as if I were a carburetor) would work to tell if a)it was an advance or retard dizzy and b)the dizzy's advance/retard worked. I sucked as hard as I could (though I can suck pretty bad sometimes) but saw not the least...
