Since the on-board generator runs off the MH gas tank contents, it gets what the V-10 gets. There's a gas station about 20 miles away that sells ethanol-free gasoline, but a 40-mile round trip at 7 mpg to buy gas that's 75 cents a gallon more than the tribal Chevron doesn't make much sense, particularly since we very rarely use the generator. At 11 years old (an '02) it only has 54 hours on the Hobbs, and I've put 6 hours on it in three years, all doing the monthly exercise.
I'm fighting the gummed-up carb issue at the moment because I was incapacitated for a few months after cardiac surgery last year. The generator wasn't exercised during that time and hasn't run since.
Reading the operator's manual, I discovered that there's a screw that allows the float-bowl to be drained, so I'll try using that to dry out the carb. On my mower, I shut off the gas as I'm finishing the yard, so the carb is dry in storage. It's more to avoid gasoline odors in the garage than to prevent gumming up. So far, I haven't found a simple quarter-turn gasoline shut-off valve for 5/16" hose to use on the RV genny.
