When I get something of unknown history, I usually do a compression check and a leakdown test as soon as I can. Especially the leakdown - will tell you a lot about where the engine is worn/needs adjustment. You can use an adjustable spark gap to test the health of the ignition system. Weak spark (dirty contacts, failing coil, etc) may LOOK ok, but can be the source of a lot of erratic starting/running. If it has been sitting (especially gas engines), flush and clean the carb and fuel system. It may seem a little anal, but replace all the filters and fluids - so you know they are ok. You can usually borrow/rent any specialized tools you need for these steps at the local auto parts house.
Then, once it's running, I go through and adjust/check the adjustment on everything (brakes, clutch, throttle, choke, steering, belts, etc.). Check hoses (water, oil, fuel and hydraulic) for cracking/damage - replace what you need to. And check all the bolts I can get to to ensure nothing is loose.
It takes a little time to go through this routine, but you get to go over the tractor and find out what shape it is in - often will find problems before they cause failures. And you establish a baseline so you can recognize problems that crop up in the future.

If someone replaced the points, check to make sure they put the right ones in, and that they aren't grounding out on the case or pivot pin or where the bolt goes out thru the case of the distributor.
Another spark killer on these is the little bar on the rotor can come off. Easy enough to miss if your distracted.
Ummm...:blush2: been there :blush2:
