How to fix the Kirby handle....
Prior to sending my Dual 50 out for the re-build through Kirby, my handle also leaned forward badly. Kirby, was pretty sly and the way they fixed it was to either hammer or "drill in" to small spiral nails (maybe these are called, "self tapping"?) while leaving approximately 1/8" or less out so that the metal "flange" part of the handle would rest along the two newly formed "rails". I will try to take a picture of it. They did not replace the fan housing! Bastards!
