Hmm.

I just went out and undid the fuel line (the one to the distributor not the pressure regulator - is this the return or the supply?) so that there's definitely no fuel pressure. Then the pin you mention which I thought was the plunger became even less keen to return, most of the time the plate could be moved very freely independent of much return pressure pushing it back - except for its own natural springyness.

I wonder if this is all a red herring and the spare unit I've got merely moves freely because it has no return pressure whatsoever - the pin/plunger is maybe stuck at full deflection since there's no fuel pressure to make it return. And therefore the plate moves freely with nothing impeding it.

Larry Delor - can you tell me how you remove the black rubber bottom half of the AFM? Then I could look to see if the pin/plunger is moving..
