Secondary Actuators, Upside down or Not - ZR-1 Net Registry Forums

In the "Dreaded No Start" Thread, I had asked about the misalignment on the secondary Actuator linkage as found on My 91.

Linkage as found

To Me it appears that it would cause binding of the linkage and abnormal stress to the diaphragm. So I removed one and tested both with a vacuum testor, neither appeared to bind in any way, and the vacuum required for full travel was the same on each one.

Actuator rotated 180 deg to straighten alignment.

I gather there are differing opinions regarding which is the correct mounting.
