That is no doubt going to be a very interesting restore...
As you have likely found, all the switches and connectors are most likely unreliable and need replacing... the wiring, fortunately is limited and should be fairly straight forward to replace...
Good luck with the project and if you have been taking pictures... post them and keep us following your progress... :smile:KennyV
No pics yet,,, did get the deck painted by a industrial yard,, even though it was like new, I've always had my decks repainted, much better primer. What surprised me most was how "clean" the inside of the motor was,, pulled the plugs and drained the oil as soon as I got it home, salt water poured out of it,,, I was thinking this is going to be ugly, but it was clean, couldn't hardly believe it, there was some rust in the bottom of the cylinders about 1/3 around for about a inch, mikes out fine though, rings were shot, but that's it on the internals,, this is after the mower set for over a year with the motor full of saltwater,,, he was waiting on State Farm to show up for insurance.
Some of the wiring will give a challenge though, trying to figure what goes where. Oh yeah the carb was frozen from oxidation, but I got it and all the butterfies freed up, looks decent, still have to have a kit though, complete engine gasket kit, rings, and I'm sure a few other items,,, we'll see.
