Not trying to change the subject or anything, but. Or is it actually back to the subject.

The attached photo shows the linkage that I use on injection systems. THe beauty of this arrangement is that it provides for a progressive rate of opening. This is due to the angel of the actuating links off of the bell crank close to the closed throttle position.

This is an injection system that I put together for a Pantera but the linkage geometry would be the same for Webers. The stand that the bell crank is supported on not only provides the right geometry location for the bell crank but it is a vacuum accumalator as well. This provides a good source for an average vacuum signal for the MAP sensor.
