I have one F Series Bearcat 55 left. I bought this one from an old gentleman who had the powerhead rebuilt and gave up on reassembling everything. I'm in that process now but need a wiring diagram! I also have two extra lower units, a frozen powerhead, and practically all of the parts to ake a complete Homelite 55. Oh yes, and 1-1/2 early chrome hood cowls, not in the best of shape! I'm in central Florida and will probably ebay the motor and then ebay the parts separately.
