Lawn mower dead

>Oil not changed in over 2 years
>cleaned carburator
>changed spark plug
>changed air filter
>tried new fuel

Lawnmower can't start... if i'm lucky it goes to start and immediately dies. Is it toast? it's a little 140 cc craftsman. I will be fined if I don't mow my lawn

    That always means the spark plug is faulty. They're all made in the same chinese factory and labeled whatever, so buy a box of 2 dozen or more and you might find one that runs more than a few seconds.

    do you have spark?
    can you get it to start with starter fluid?

        headed to a client right now with a new carb after doing everything including the coil. jets are clogged but there is no point in rebuilding kit for jets (~$18) when a full new carb with seals and everything else is sub $20.

        I've had this damn thing apart 20 times over the last 3 weeks, finally got spark with a new plug and was fricking pissed when it still didn't run. if this carb doesn't fix it I'm going to lose my shit. good job by the way, I realize I'm posting in a solved thread but it's the closest thing to relevant.

    Carb not properly cleaned, some channel still blocked by dried out goop, clean all small channels with brushes from steel brush. Also check fuel filter, it might be blocked. If it worked last autumn there is no reason it should not work now.

      Fuel left to sit over winter clogs the carby, people forget to empty the tank before storing it because they don't consciously decide which will be their last mow in the winter

        No it doesn't. Emptying the tank is what causes it to clock because the gas evaporates and forms varnish.

          literally wrong. left sitting with gas == problem. run engine dry at end of season == no problem. get your shit straight you fricking homosexual.

            Just pull the gas line and collect the fuel into a container.

            I bought a new husqy mower 9 years ago along with a cheapo stihl weedwhacker, never emptied the gas in winter on either and they both still start up just fine every spring. We get down to 0F every year too, these are not mild California winters.

              Don't know about your engine but like the other anon explained it might be self-draining, and colder winters HELP as the fuel will stay longer without evaporating. It's not like the engine gets cranky from having been left in the cold for too long...

        Thats why i said clean your carb, they dont go in to a disrepair after a winter would have been more accurate I guess.

        No it doesn't. Emptying the tank is what causes it to clock because the gas evaporates and forms varnish.

        Bro, the small varnish you get from a carbful of gasoline isn't enough to stop running. When you leave tank open and it keeps feeding more gasoline and therefore more varnish is when you get issues. If you get it running eventually the new gasoline cleans up the varnish from the carb.

        Occasionally get to use an old lightweight MTD. Briggs 3.75HP it says. Carb design drains back to tank on shutdown, tank under carb. Means it always has to be primed, but also means the carb never has fuel sitting in it.

        Left it in the shed last fall, this summer started right up.

    start and immediately dies.

    OK so that narrows it down.
    Are you starting it up on choke? Is the cable for the throttle tight enough to engage the choke? Is the air filter full of shit? That often causes engines which start to cut out.

    Usually you buy a carburettor kit online which has a new spark plug, air filter and carby, and you just install the first two and see if it works, failing that you install the new carbeeuretor.

      I just unearthed one that's been untouched in my parents' basement since before they moved in 30 years ago and probably dates back to the '40s or '50s, all wood and cast iron and weighs a frickton. Shockingly despite being rusted to hell it still works halfway decently, took a few passes to get a good cut but their back yard is also overgrown to the point where it's like a foot long.

    if you put gas on the air filter, will it run? and I mean a good healthy splash, not just a couple drops. if it runs then it's your carb

      It's a Briggs and Scrotum issue and it's complicated further using "amazon" replacement carbs.

      >Take off carb
      >cut and punch out holes (with your dank HF punch set) that match your old gasket using a "gasket making kit"
      >Throw carb in 1/2 pinesol, 1/2 water (of full pinesol if it's being extra Briggs and Stratton on you) with the float bowl disassembled for a day
      >reassemble
      You're welcome. You can buy a +10$ gasket everytime if you want, but this way you can now make even more gaskets for less money the next 3-4 times this happens (it will). Plus you're future proofed for the next EPA certified perturbing device or any others because you can make any gasket.

      really? briggs and stratton are that bad? WTF

      Yes. Always.
