Well, my new starter for the old tractor did finally arrive - a day late, but it came - and I got it installed yesterday.
I also replaced the old fuel filters. FYI - the filters, which are two dollars apiece on line, cost twenty one dollars each at O'Reilly Auto Parts.
Anyway, I thought I was done, but the old tractor only ran for about 15 or 20 minutes, then shut down again. I've still got an obstruction in the fuel line somewhere, I just haven't pinpointed the cause.
Installing that starter proved to be, quite literally, a pain in the ass!
At my age, I'm used to having new aches anytime I do anything outside of my usual routine, and I had to hold the starter in place in a very awkward position with one hand while I started the bolts with the other. I knew I would be feeling that today, but I expected to feel it in my arms and chest. I do, but by far the most noticeable pain is in a totally unexpected area.
I installed the starter from a sort of kneeling position, sitting back on my heels, and this morning my poor old butt feels like someone was kicking me the entire time.
