Genset carb upkeep:  drain it and/or exercise it? Both?

Matt, thanks for that map -- incredibly, I live ten minutes away from TWO of those scarce ethanol-free gas sources. It never would have dawned on me that auto racing supply companies would have their own special gas pumps!

I guess there is an upside to living in a huge dense urban area like Southern Calif -- the goods and services available are nearly unlimited. (And so is the traffic.)
