Pull the cap off the distributor and verify the automatic advance is free. Then put it back together. Look in timing hole and rotate the engine slowly until you see the 26 degree mark. Mark it with a crayon, Magic Marker, etc. Then, put a timing light on the engine hooked to #1 cylinder. Start it - run it at full throttle and verify it's firing at the 26 degree (BTDC) mark.

Keep in mind that is the factory specs. All factory specs are compromises and some engines run better adjusted differently - much depends on engine condition, fuel octane, the altitude you are at, etc. So, the Deere 26 degrees before top dead center for full advance is a starting point. Then, if you feel the tractor lacks power, hesitates when you throttle it, etc. you can advance a little more.

Some tractor and truck companies - e.g. International Harvester - give much more complicated timing spec charts with fuel octanes or cetanes, feet about sea level, type of useage, etc. Deere never did that.

In order to start and run properly a gas or diesel engine needs to have different timing settings at different engine speeds and sometimes at different work-loads. 1010 gas engines use an automatic timing advance that works by centrifugal weights in the distributor. When you pull the cap off, you can check for proper movement. If you try twisting the rotor back and forth - it should move a bit and be separate from the main distributor shaft. You are supposed to oil it once in awhile to keep it from getting stuck ( a few drops on top).

If your 1010 is working properly, the timing should be around zero degrees at engine cranking speed - and advance by 26 degrees when revved up. If you have a timing light with a built-in degree wheel - it makes things real easy to check. I'd explain but don't want to confuse things here.

1010 diesel has an advance that is hydrualic instead of mechanical and works off a rise in internal injection-pump fuel pressure. You can also check the diesel with a timing light - but it requires and extra "pulse" adapter that gets hooked to an injector line. Not needed though since it can be checked with a $5 plastic degree window you temporarily bolt to the pump.
