I just wanted to share a realization I had on owning a propane or propane/gas generator:
I bought a Duromax 4400EH (Propane/gas) a while ago. I don't use it much but make sure to test it every so often. In the past I would fill it up with just enough gas to get it going and test it. Then I would have to drain the extra fuel when done because having it sit in the lines isn't good if you want it to be reliable. Typically I'd use the hose and primer bulb method from Steven Harris to pump it back into the gas can, lawn mower, snow blower, etc. Then run out the remaining.
I went to test it yesterday and thought, Why the hell mess with filling and draining gas when I can just hook up my propane tank. I felt like an idiot not thinking of it sooner. It made the test process a lot less cumbersome. And I don't have to worry about fuel left in the lines.
Other benefits:
-Propane takes up a lot less space when storing 20 gallons
-It lasts longer
Regarding the battery for the key ignition:
-Disconnect the terminals when not using it for longs periods of time. (More than a week?)
I've left mine connected and every time I test, the battery is dead. I may need a new one but the lesson is learned.
-Why get a gas only generator at all?
The price seems to be a difference of 55 dollars
Gas only:

http://www.amazon.com/gp/product/B009RBKGZC?keywords=xp4400EH&qid=1444575889&ref_=sr_1_1&sr=8-1I was kind of eager to get this one because it was on sale when I got it. $500 vs $650. And Now I see it's on sale for $465. I think I would spring for a 10,000 or more when ever I have to replace this one. And I'd definitely look at getting a Honda or Yamaha.
