    So, the TL;DR, you should be fine with whatever gas you choose. Just make sure to keep it fresh and don't let it stagnate in your lines/carb.

    I run premium in my personal riding mower, but we run Shell regular in our fleet. The bigger factor you want to take in is fresh gas. Is your local premium fuel constantly being used and restocked, or does it go a while before it's restocked? Your local gas station manager should be able to help tell you pretty much how often it gets brought in. Fresh regular grade will always be better than stale premium. Another factor is maintenance. Are you changing your fuel filters annually? You should. Fuel treatments also help. I'm able to test my fuel in my shop or garage and tell exactly what the ethanol percentage is. Most stations are here are around 9%-11%. With that in mind, we know ethanol has cleaning additives and attracts water.

    WATER is your fuel systems real problem - not solvents. The ethanol additives will stiffen up diaphrams in your carb or vacuum operated fuel pump, but we have measures against that like fuel treatment and properly storing equipment. The best thing to fight against the water build up is some Mechanic in a Bottle. This stuff chemically encapsulates every water molecule in your fuel and allows it to pass through without corroding your fuel system/carb or clogging your strainer/filters. If you really want to be a fuel nerd, look into b3c fuel tests. They have everything from cheap fuel swabs to check age and for water to all out fuel and oil test kits.

    If you only mow once or twice a month, turn off your fuel valve at the bottom of your tank and run the engine until it dies. This will keep fuel from stagnating in your pump or carb, and then you can pour a little bit of that mechanic in a bottle in with each tank fill up to really keep it fresh. You should never need a carb rebuild if you do this. Granted, that can be extreme, so if you at least do that with each winter prep, you should still be ok.

    Would you mind taking a picture of your carb tomorrow? I'd like to see something.

    Our boats, generators and off-road toys sat for extended periods during the off-season.

    I stopped having fuel related issues once I started using this.

    ^^^^ I swear by this myself. Add it to every gas can I fill up. Please note: just because it’s high octane doesn’t mean it’s ethanol free. Use 87 octane and add the Sta-Bil. If you can find 100% gas (no ethanol) 87 octane even better but premium gas in a lawn mower is a waste of money.

    No, you gotta pull off the air cover on that one. The only real issue we've seen on ours is a few started running rough. It turns out a welch plug on the carb came off and my rep told me they have been seeing that on a few. Right now the fix is installing a new plug (I think they're .20, but that would be covered under warranty if you feel like trailering it out and going back to pick it up) with red thread lock on the edges. Real simple fix. I was just curious if those smaller models ran the same carb.
