RE: Should elevator move same in both directions?
If Im understanding the question correctly, the answer can depend on whether or not you have enough up and down elevator throw according to the instructions.
For example; say you can move the elevator up 1.00 inch and down 1.13in but the instructions only call for .75in, then you dont have a problem. But if the instructions call for .75 inch and can only get something less, then you have a prob.
Cheers.
