Many thanks everyone. Yes, I'll be leaving well alone for the moment - I've got a year to worry about it in, so no need to do it all now!
So the Haynes statement that the voltage will fluctuate rapidly so watch carefully, is a bit misleading, given that you say the real underlying fluctuation is actually too rapid to pick up on an ordinary digital voltmeter.

I just tried it again, having got the engine really hot climbing a hill. The hot resistance had come up a bit, to 8 Ohms, I so I guesss that is OK, although not the 13 Haynes says.
But I didn't get any voltage alterations this time on reving the engine - it simply kept going through its idling cycle, all readings in about one second intervals from 0.1 to 0.9V. Engine speed made no difference.
I tried pulling off the vacuum pipe to the flame trap and it hesitated and voltage fell to 0.1 (ie weak). Then when I put my finger over the hole it rose to 0.9 (ie rich). So I suppose that means it can detect mixture variations correctly.
