Pretty much it. Mine don't have electrical shut off because of magneto.
To start:
1: Diesel on.
2: Gas on.
3: Gas in gas tank.
4: Lots of gas in gas tank.
5: Throttle off.
6: Push decompression lever forward. (Gas mode, at least on mine)
7: If you didn't hear a snap from the butterflys, do it again.
8: Shifter in neutral.
9: Clutch down. There is a little latch to hold it down, but I don't like using it.
10: Ignition switch on, if it has one.
11: Choke on.
12: Hit starter.
13: Count two cylinders.
14: Push choke part or all the way in.
15: Engine will start to fire on about 3rd or 4th cylinder.
16: If choke is still on, it is now flooding.
17: Engine will cough a bit and then settle down.
18: Once running, wait one full minute if a cold start. (Hmm, is that tank full enough?)
19: If already warm, no wait required.
20: With one hand, pull decompression lever, then raise throttle. Too quick and it will spark knock on residual gasoline.
21: You are now on diesel.
Per the book, the shutdown procedure is:
1: Set throttle to about mid speed. (They don't really say this one)
2: Ignition switch on.
3: Pull down the throttle.
4: Engage the lever, switching it to gas.
5: Turn off gas.
6: Run until carb goes dry and it quits.
7: Switch to diesel.
The part they leave out:
4a: If running on gas, go on to step 5.
4b: Switch back to diesel because gas didn't take. Carb bowl is dry. See below.
4c: Go back to step 1.
The real way to shut it off:
1: Throttle down.
I have to say this method isn't quite as easy to start, but the difference isn't all that much. BUT, it eliminates that part where you almost always forget to switch it back to diesel.
Observed rules:
1: Unlike a gas tractor, on a start the intake manifold has been swept clean and has no residual fuel in it, so be patient.
2: They flood fairly easy, but almost always require a bit of choke even when warm, so there is a knack to be learned.
3: While running the carb float is shut off. Eventually the carb will go dry if you run it long enough and the switch back to diesel will be less than successful. On a second or third attempt the bowl will finally have enough time to get enough gas to run. Remember that gas doesn't flow until the lever is in gas mode, so you are using the coast down of the engine to fill it.
4: NEVER leave the decompression lever in gas position after shutting it off. They have been known to warp starting valves faster than you want to think about. You may get lucky, but you may not.
5: The starting tank will last less than 10 minutes even when filled to the very tippy top.

Today's Featured Article - An Old-Time Tractor Demonstration - by Kim Pratt. Sam was born in rural Kansas in 1926. His dad was a hard-working farmer and the children worked hard everyday to help ends meet. In the rural area he grew up in, the highlight of the week was Saturday when many people took a break from their work to go to town. It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer. It was an Allis-Chalmers tractor dealership,
