    Yeah, I might have done that if I didn't have a time limit looming. I'm usually too stubborn to even begin a job like that if the clock is ticking and there's another way to solve the issue temporarily. The wife needed to be able to get out to go to work on Christmas Eve, and we were expecting guests later in the day. I'm just not willing to put that pressure on myself. I've crapped out trying to "fix" so many things, my handyman confidence is very low these days.

    Now we just pray we don't get another snow dump in the next week or so. I do still plan to rebuild my original carb though, so I will learn something.

    This is a good option to learn on. The carb should only have the one jet and one idle circuit opening.

    Best way to clean is with a carb cleaning solution (the one that has a basket and you soak the parts in) but for this job a can of carb cleaner (spray) or even brake cleaner should cut any gunk. make sure you blow all the passages after spraying so yes wear eye protection at a minimum!

    New carb is in, and she runs like a champ! I notice too, it says don't use fuel with more than 10% ethanol. Does regular 87 have more than that?

    I'll tear into the carbs sometime soon, and post up what I find in there. Definitely using no ethanol fuel in the future though. Bring on the snow!

    Virtually all the fuels today have @10% ethanol. Federal regulations require a minimum of 2% in all unleaded fuels. Most blends don't exceed 15% due to falling into the E15 category which generally requires specific pumps, etc. that many stations don't have or don't have room for. Unless the gasoline is listed as Ethanol Free it has between 2% and 10% ethanol guaranteed.

    I started buying the ethanol free for my small engines (riding lawn mower, weed eater, chain saw, push mower, etc.) several years ago and immediately noticed the gasoline didn't sour as quickly when buying a 5 gallon can. I also quite having as many hard start issues after the equipment wasn't used for a week or two. Started putting Ethanol Free in all my vehicles that don't get driven daily and don't have any long term storage issues or hard starts even when I forget to add Stabil or other additives to the fuel.

    Have had good luck using fuel stabilizer with my local pump gas. And if your machine doesn’t have a fuel filter, install one. They are cheap and easy to replace.
    just imho

    My mower has a little thing that gradually adds stabilizer to the fuel on its own. Probably a good thing to remember to maintain that.

    The gas I put in my Zeph I know is non-oxygenated, but maybe that doesn't mean the same thing as ethanol free. I'll have to make sure. I'm going to dump the remaining 87 in my small engine can into one of the DDs and refill it with the non-oxygenated. Hopefully I'll be able to find out for sure it doesn't have ethanol in it. Stupid corn.

    Non-Oxygenated fuel should mean Ethanol free.

    Never seen or heard of a mower that adds stabilzer to the fuel on its own. Interesting! I have seen the 2 cycles that add oil to the fuel, but that's about it.

    Being retired, am not driving nearly as much as before. Full tank lasts a month or more.
    Going to pay a bit more and check out running non ethanol fuel. The street versions.
    Looking at local major brands, even one Kroger station.
    Chart shows the corner gas station sells some, was unaware of. Others right under my nose.
    Was not aware pure gasoline was sold at so many locations around town if one knows were to look.
    The local list here has a lot of marinas but list familiar drive up stations.
    For trailered boats, off road vehicles, HO or race cars. Did not know has longer shelf life.
    The MN list checks out: https://www.pure-gas.org/index.jsp?stateprov=MN

    Now to not let out what i thought was summer heat causing visual pressure in plastic mower fuel containers.
    All that does according to articles is lets out the good stuff thus helps stale the fuel.

    Mainly in the summer, area near a parked hot old carb car can smell like a bar or beer.
    Dam ethanol vapor from carb or antifreeze leak. After a bad front end accident too.
    Impossible to explain that after being pulled over and cop walks by front of car. Happened several times.
    Once had a blown heater core dripping on pass carpet and windows steamed up. Cop searched for non existing open beer.

    Neoprene rubber fuel lines also are not designed for ethanol gas. They do make submersible rubber fuel line that I use for fuel pumps.Got it at NAPA.
    PTFE fuel lines are ethanol gas friendly.

    Marine grade fuel line specs look pretty tough.
    Noticed lately local station price sign has zeros where ethanol price was.
    Now they stuck signs in the grass stating "We sell ethanol free gas".
    Will have to check to see if that is at all pumps or a special one in back.

    If by chance you have access to LL AVGas it is perfect for engines that don't get run often. Not "Legal for street use" as most things for car engines but it has everything already in it.
    You can fill a tank and let it sit fir months and months. Prime it pull the start rope (or switch) and they will crank right up..
