Okay, so I've made some progress, but I'm not out of the woods yet. I took apart the carb and the gas valve and low and behold what did I find -- the gas valve was assembled backwards. Previous owner (???) or someone on down the line installed the plug in the out port and the 90 in the in port, so what was happening is that the fuel would come from the tank and bypass the sediment bowl and filter. Obviously it ran quite a few years this way, and I think the only saving grace is someone had apparently stuck a wire mesh filter up above the valve into the tank. So I replumbed the fittings and cleaned them out as best I could. Also cleaned the carb out, since I knew it had all sorts of sediment-style junk in it.
Put her back together for a trial run today but the gasket around the sediment bowl is shot. As soon as I fired up the tractor, the bowl started to weep around the glass and drip down onto the clutch. So I only ran it briefly. I picked up a new gasket and filter on my way home but haven't put them in yet.
The only downside is that even though the tractor did fire right up and run, it still seems to be running rough. Didn't have time to try and tune the carb adjustments though, so we'll see if that makes it any better, but I'm not very hopeful. What throttle position are you supposed to tune the main jet at? Seems like as soon as I crack the throttle open from idle, it starts to run rough, and putting it in gear to move it seems to make it choke and starve for a few seconds before it sputters back to life.
So whether or not this is the root cause of my problem or not, I am at least glad to have this issue that I didn't even know about fixed.
