Care and feeding of my ex650?

I got one of these nice purring little gennies used, and now I need to know what to do with it!

I have zero experience with small gas engines. Never had a gas lawnmower.

I dumped the gas out of it and ran it dry, on the suggestion of a friend. Now, should I get special ethanol-free gas for it? Or can I use regular? I suppose it predates unleaded regular...?

Should I add stabil? How much?

What do I need to do in terms of ongoing maintenance?

I think I can print out a manual, but I figure some of these aspects (like what fuel to run) will be outdated and I need to ask you guys.

I did get a gardening knee mat to put under it, on the advice of somebody here (smkettner?) but I don't have a rear rack for it yet.

    First things first.... put some regular fuel in it, run it for about 10 minutes, and then drain the engine oil and replace with some good synthetic 5w-30 motor oil in the crankcase. Not sure if it takes 1/4 qt or about a 1/2 qt per oil change. Oil needs to be hot, hot hot and mixed up/homogenized from running before draining out and replacing.

    Additives to fuel... Stabil should be in the fuel, 1 oz per gallon, or get a 6 pack of Chevron Techroline at Costco. Needed to keep the jets unclogged if you don't use the generator regularly. Read the label for mix ratio.
