Update, I tried the vacuum test with the slider in various positions near the home position, and it is all the same, no matter the position. I have about decided to use it like it is. The leak is very small of course and worst case I will have to adjust the idle jets a bit. Off idle it won't be noticed.
Also I should clarify, all this is not meant to be critical of Wiperman or his work and service to our hobby. I am just trying to find out if this leakage is normal for a rebuilt motor.
Thank you for all the comments.
