That was well worth the $20 u spent on it. OK let's see....someone replaced the original steel wheels with goofy plastic ones. They are often on ebay or, where I got mine, castomowerparts.com. Fronts are 7x1.5 and rear are 9x1.75 (or 9x1.95 if u can find them). I'm not sure about that wire because I have removed it from a couple of my mowers and they still run, although I haven't tried starting one without a chute on so perhaps it is in some way connected to that. The mulch covers are about $8 and the side-discharge chutes are about $23 online. It probably just needs a good carb cleaning. With a little cleaning up (and some steel wheels!) u got a beast of a mower! Good find!
