It's only a recent fluence that has been cast upon me by Mr Karma. Before that, I seemed to keep everything running just by cussing a lot, administering a good kick and / or, a squirt of Servicol. (So, long ago, I can't remember the spelling)
As mentioned above, the Sears guy billed me for $180 bal zero, for looking at it. The $600 bill that the last guy printed out is a total mystery. They've assured me that I'm not paying.
