I hate to sound like an idiot, but can anybody give me an idea what the solenoid looks like or how to find it? I don't have a clue.
My hunch is that it's the ignition switch. A few months ago, the key started getting sticky when I started it, like it was gunked up. You turn the key to "start" and when you release it, it just stays there, you have to deliberately turn it back to the "run" position. Later I will get some metal panels off the tractor and just follow the wiring from the key to the starter and see what I can find. There are areas back in little nooks where there's a 30-year buildup of goo.
Looks like I won't be getting another small tractor, at least. This thing just keeps running and working forever. I need to clean and tune it - it's been 15-20 years since I changed the air filter or plugs or oil - I've never adjusted the belts or anything else on it. I've cut everything from grass to 5-foot pasture ragweed with it, and towed a 50-gallon boom sprayer with it for days at a time. And it still runs and works like it did the day it was new. What can I say.
If it's of any interest, the tractor is a "Craftsman II" 13HP. 42 inch cutters. Model number starts with 917 - it was made by "American Yard Products," whoever the heck that is/was. It was made in 1985-86.
The motor is a B&S I/C Gold, model # 28M707.
The tractor looks exactly like this one, found on Google Images.
