I guess I'm extremely lucky
I kill the gas valve and let it run out.
I put fuel stabilizer in the tank with the existing gas. I add new oil before I use it again and it starts right up every time.
I use non ethanol gas on small motors, might be a reason

Ive had this generator since 08.
Last time I used it was 2017 and I cranked it up on the 4th pull and was rolling 4 years later. Loaned to a friend Monday morning and it's still going strong.

I drain the gas then run the trufuel 4 cycle fuel in it till it runs out. usually a 1/2 of the can. Then I run that once a year with the 4 cycle trufuel. The container said its good for 4 years on the shelf or 2 years after you open the container. Been doing this for a few years and haven't had a problem on my stored 4 cycle equipment like my generator and pressure washer.

I have no idea if this is recommeded or not, it is just what I've done with sucess.


I started doing the same couple years back and so far all my equipment fire right up when I need them. No carburetor issues

Isn’t letting it run till it dies the same as draining the carb?

I’ve had the same generator since before Katrina. All I do is let it run itself out and then put it up.

Coleman Gen with a Subaru motor. First or second pull start every time and purrs like a cat.

Think I’ll add seafoam this year though. Good idea.


In my experience, no.

The volume of fuel left in the carb and bowl is still enough to leave behind deposits and gum up the carb.

Sea foam could help but it is best to get rid of that fuel.

This has become enough of an issue that newer Yamaha generators come with a separate float bowl drain valve to drain for storage.

Same here. Kill the supply and run the carb dry.

This really a version of the “store it full of stabilized fuel and start it occasionally” plan.

The trufuel is highly stabilized and likely not leaving behind many deposits when it dries up in the carb over that year.

I still like draining the carb entirely if it will sit for that long.

But if it’s working for you the. I say keep doing it.

Switched to a dual fuel a few years back. Running propane only these days and never looked back. Gas as backup only.

If in NOLA you should wait until we are connected back to the grid.

Think it may be a long few months with some rolling blackouts or that power generation going down.

Store the frigging generator in Tennessee where I am moving after this clusterfrick.

This. It'll be OK for a couple more months. Try to crank it up every couple weeks though.

Why...?

You want to pull it out once a month and run it...

I leave mine full to the brim of treated fuel. The tank rusted bad once when I left it empty. Louisiana humidity will permeate tank and rust it out if stored empty. It cannot rust if stored full of fuel.

With generator running turn off fuel valve and allow to run out, which drains plumbing to carburetor. Carburetor will not fully empty by just running until it quits, so you have to get the rest of the fuel out. Open drain on carburetor bowl. If no drain remove the bowl to drain remaining fuel. It is now empty and there is no fuel to evaporate and leave behind the gunky residue fuel deposits that clog orifices and dry out rubber or plastic parts of carb and fuel system.

Do not drain oil.

My generator is ready to go every single time by using this method. Your mileage may vary.
