The Blades Aren't The Same - Attempting to Revive a Slow Lasko 3733 Box Fan with Marco Motor | Day 3

Attempting to revive a 1999 Lasko 3733 box fan with a Marco shaded pole motor that's running significantly below spec for unknown reasons. This is a fairly common problem with these motors, but the issue is typically limited to the medium speed. This one seems slow on all speeds. I have made some progress with the repair of the switch. I bent all the contacts back to where I think they should be and glued the switch together, leaving it clamped overnight to adequately cure the glue before applying any stress to the glued areas. The 4 motor leads are securing properly into the switch and making good electrical connection. The lead wires to the plug are still a little flaky on the high side. The contact appears to be slightly defective and isn't pulling up far enough to hold. I am going to fold the wire over and re-tin it, making it twice as thick. This should cause it to hold in the switch properly. I decided to try swapping the blades between the unit in question and the one that my grandfather bought that still works properly. This was a very interesting comparison, and it turned out that the blades are not completely identical. I'm starting to think that the unit in question is only defective on medium like all the rest of these Marco motors and that the performance and sound are different on low and high because of the difference in the blades.
