My 961 (Ford Powermaster 901 series) acts up when it gets warmed up, such as when I'm pulling a plow or disc, or the weather gets above 70 degrees or so. It runs fine when cold, but then the engine sputters and dies (if I let it) as it gets warm. If I choke it when it's acting up, I can keep it running long enough to do a few more minutes of work or get it back to the barn. I let it cool down for a few hours or overnight, and then it does the same thing (runs fine for 5 to 30 minutes until it gets warm, then starts in with the sputtering and dying).
I believe this symptom started rather suddenly, last fall before I stopped using the tractor for the winter, rather than developing slowly over time. I don't have any history with the tractor yet, though - it's new to me, so it's hard to say for sure if this started suddenly or developed slowly.
I know it needs a tune-up, but this doesn't seem at all like the kind of problem that new points and plugs are going to fix. I'm not a mechanic or engine guy at all, but I do have a few tools and would like to learn how to diagnose and fix relatively minor, common problems in this and other old tractors. So, any hints, ideas what to look at, pointers, etc. are welcome.
Thanks,
