Question about Husqvarna Lawn Tractor - 54in. Deck, 26 HP, Model# LGT2654

1 Answer

Engine stops after ~ 15 - 20 min of mowing

After one year of use (a season actually ), cold engine starts OK. After some mowing ( time varyies), the engine's rpm starts varying ( wavy sound ), slows down and dies. I let it cool for some time and it starts OK again but this time it takes less time to die on me; and so on until I quit trying. I had the same problem with another unit, a year ago, but it happened just after I bought it so I returned and replaced it.
Help!

    I have the same problem, i bought a mower in 11/08 that is an 07 model, l bit more information on the prob is the mower has about a years worth of hours on it 38 and if fine cold but after 20 min it wont handle a load but will idle, i changed the filter and same prob. Lowes change the plug, filter, and did a tune up kit supposidly on the carb and found nothing wrong afterwards so they sold it to me at a discont. Not sure of their service persons test but the unit will idle all day just wont handle a load long. The consumption is more than will feed. the carb has an electronic shut off on it and i feel that the float is sticking so it is senseing that it is flooded when not it is starving because the filter is sucked dry. The lines are clean with a new filter, it gravity feeds fine. It seems that it is vapor locking but not sure normal tricks dont work. it must be the electronic sensor on the carb. I just hate to tear into a new mower that lowes was supposed to fix especially when it appears to be a common problem, what do you think boscia with this information. Those suggestions are common fixes in the perfect world.

    We just rebuilt our engine after 486 hours, it smoked and that was the only issue. Now it will run, but won't cut under load. Acts as if it is flooding. I just rebuilt the carb and the same thing!

    I'm think the valves may be to tight. What are the spec's for valve adjustment
    and do the aluminum push rod go on the int or ex?

Try changing the spark plugs. if that doesnt work check the fuek lines for hole and leaks, check the fuel filter and clean if necessary. remove the carbuerator and inspect the gasket; it should be soft and flexible, if it seems hard or brittle replace it. clean the carb with carb cleaner sray (available at any local auto parts store) and compressed air. make sure you get inside the small fuel rail holes.

Engine starts, runs for a few seconds and stops. After many attempts it starts and runs. I turn it off and want to start, same all over again. What is wrong?


Off the cuff, I'd guess the carburetor is gummed up.
Gasoline is not good stuff. If left in a mower tank, it can evaporate over a year's time, and leave a gummy mess.
It can also "sour" and lose it's volatility.
It is a good idea to run the tank dry at the end of the mowing season, (if you have one,) and start fresh the next year.
Car parts stores sell cans, (about a pint), of carburetor cleaner you can add to the gas tank.
Try just a little of it, about a few ounces, see if that helps.
If not, try a new spark plug, before you go to the expense of a carburetor rebuild, which can cost up to $ 100.
God bless your efforts.

sounds like, a valve clearance adjustment problem. starts when cold, looses some power when hot, if turned off or stops, won't restart until cold.

I'm not sure of the model number of your mower or engine to know the fuel and carburetor set up. I do have one easy thing to try though as it sounds as if a vacume is building up in the tank. Try putting a half of tank of gas in it, leave the gas cap off, and see if it continues as it was or if it runs ok. If this stops the issue your cap vent is pluged up. I hope this helps

If there is an anti fire solinoid on the base of the float bowl you need to check it functions ok, unscrew it from the float bowl, switch the ignition on, the centre pin should retract fully into its housing, if not it will shut off the main jet in the carb and cause all sorts of problems.

First, I've had a motorcycle for almost 50 years and have never drained the gas. At one point it was not used for 3 years. It started, I added gas and it ran fine.
Second, next time you are running the machine and it begins to stall, immediately loosen the gas cap. If it starts to run good again, drill out the air vents on the cap.

Try taking the cover off to get to the fly wheel and use some fine sandpaper or emery cloth to clean off the magnets on the fly wheel and the two little prongs that set really close to the fly wheel.
My white wouldn't start right away and I did the above and now it starts great.

Let me know if that helps.
