I run a old school 3kW non invertor genny.Use Fuel Stabilizer in your ethanol-free fuel. And when you shut off your generator, go it by shutting off the fuel so it runs the carb dry.
Generac with made in usa Briggs & Stratton motor. Noisy, yes.
But with enough surge capacity to start the natural gas furnace glow ignitor while also running the freezer and household LED lighting etc.
Or run a skill saw or air compressor on off the grid construction jobs.
But, yes, one step more I use for reliable start after storage.
While just a bit of gas left in the tank, mix in some SeaFoam at prescribed rate of solvent, shake machine well.
Ride choke so it will stay running on the solvent mix.
And run with a hair dryer load until it runs dry.
Hair dryer speeds the run dry time.
Then drop the carb bowl and toss the last bit of fuel there
I buy CTC supreme grade fuel, allegedly Ethanol free. Then stabilize it.
Usually I fill the cache in mid July before thunderstorm storm risk season comes to town.
Then we consume the over wintered cache in our cars in March when winter storm risk has passed.
I have fleet of 16 Coleman white gas cans that I have rust resist sprayed the tops on.
I use these as my first line of over winter storage stabilized fuel, kept on a shelf under the overhang of my back yard shed.
I have learned that trying to wrestle a 10l or larger red gas jug to fuel a genny in winter wearing gloves is not a very easy thing to do without spilling.
Smaller multiple cans for the first effort of getting gas in and the machine running after a power fail is a much nicer experience.
