Theres a lot that could cause it to not start w/out either. It could be injection pump timing, the head needing work, improperly adjusted valves, compression rings, or a bad starter or something in the electrical system not turning it over fast enough. Also, check the transmission and the fluid levels (use his manual), esp the rear end, the final drives, and the hydaulics (after running it around for a while of course). I have a 7000 (a 200 in different sheet metal and beefed up through the drive train with a 3spd powershift) and it is a great tractor. The 301 is a very good engine, very well built, it was making power that most other companies were using 400+ cubic inch engines for. Allis 301s do not start very well though, because their pistons use 2 compression rings which are shaped in a way that does not seal very well at cranking speeds, so it can take 10 seconds to start the tractor when it is in good shape at 50 degrees unless it has a "truseal" (I think that is right) or as it used to be known, the M&W overhaul kit (because M&W used to make them) which has different shaped rings that seal better at lower cranking speeds. Check it over and try to get a good price on the tractor. Also, try the unofficial-allis board, there are a lot of good allis guys over there. The compression rings would be the last things I would think, there is so much it could be instead that is easier to repair.
