Thanks to each one of you that responded. First call this morning was to Then and after. Very, very nice people. My complaint is extremely common there. They are several months back logged for rebuilds but did have the kit for my original 40217 model (thank god I kept it). They boxed it up and sent it within a hour of my call to help me. Fantastic people. Baffling, that the big box stores sell these knowing of the complaints yet nothing changes. Again, excellent advices guys, I'm going to buy a spare also.
