Convert it to propane as I did. Propane doesn't go 'bad' as my stored gasoline did.
Its a little honda 2000 that I have had for some 15 years and abused. I need it for certain events where I either run the booth, or run the RV or both...for a week at a time.
Not a bad idea on converting to propane for the property but would need a bigger tank than 150 gal and at 2.50+/gal at times, a real wallet drainer.
