Neigbour's daughter and SIL were gifted this 700 series from their neighbour who was moving away. Told there were issues. Suggested it was 2 or 3 tears old, lol, as tecumseh finished in 04 or 05. Apparently he had it running once but now it's blowing fuses whenever he tries to start it. I took a look a few nights ago and now it's in my yard. What I know so far. He bought a new battery. During his tries he managed to burn out a nice section of the battery post. Darn, haven't noted whether pos or neg. He showed me where he had spliced a new section of wire in the feed from the alternator. DUH, I'm slipping. Just typing now that I realize that could have been the diode. That might explain blowing fuses eh. Well I should get back to it before putting much more here. I will say the rest I know at this point. There's no evidence of any burned wiring other than his splice to stator. I figured that enough current to burn the post would have burned a bunch of low gauge wiring unless overload was only in the circuit from battery to solenoid to starter. I had started to think a short in activation cycle in starter solenoid was blowing fuse and maybe providing a high resistance in starter circuit. Despite cleaned exact level oil I wanted to rule out hydrolock causing starter over draw so we pulled plug and I just attached a booster pack to crank. It cranked fine but smoked at the fuse. Loaded it on the trailer at that point. Going to disconnect the stator from the circuit tomorrow and see if the smoking fuse doesn't happen. Also heading to the tecumseh manual. will update
