I also noticed it is getting harder to find information on the older units. Heck sometimes finding information on new units isn't much better. I have to download pdf parts list for poulan mowers that were turned sideways, and in french, because they came from a Canadian site where the mower was supposed to be sold, but ended up in my local Menards. I have even had to call Husqvarna tech support to get parts list for poulan push mowers that had been sold at Walmart for 6 months, and they had to go pull the paper build sheet to find the part number, because they hadn't produced a diagram for the dealer network.
