So you are saying that throttle position has no influence on the signal
you mention? By opening the throttle more, this signal does not get
exposed to more manifold vacuum?

You can. Instead of buying an expensive fuel mixture guage (as sold by
Moss, I think) you can use a cheap O2 sensor and a VOM. There is a
webpage describing this in detail. I might be able to dig it up on my
machine at home if need be.
