I have an XT721F self-propelled, auto choke Husqvarna mower. The first time I used it this season it ran for a short time and then just quit on me. I have since emptied out all of the gas and have replaced it with high octane 91, and have also added Seafoam to clean out any other issues. I mowed two weeks ago with no problems and went to mow again today and only made it through 2/3 of my back yard and the mower stalled out on me again. What's going on?

Your carb is most likely plugged from the fuel attracting moisture and turning to gel. The problem is all the newer fuels with added alcohol were never meant for lawn equipment.

You can try taking the bowl off the carb and cleaning the bowl interior the float and the main jet. Which should be up inside the bottom of the bowl. *(I think you need a hollow ground flat blade screwdriver to extract the jet) Take a soft wire brush to the jet to clean it and look at all the holes in it. Are they plugged? Cant see daylight through them? Get a small piece of fine wire strand and clean the holes out! Put her back together and run some fresh fuel through it.

Good luck and be careful!

Have fire coming out exhaust& backfire. How do I remove the flywheel? how do you time it?


More or less, check your rings... sounds to me as if your rings are going...

Fire will also come from exhaust if too much starter fluid is sprayed..

Use carburetor cleaner instead

Follow the cable to make sure it isn't stuck. If the cable moves freely, check that the flywheel brake and any attached springs are connected properly. These are usually under the pull start cover.

Just bought this mower honda hush arena 21 " push mower and it throws clippings all over the deck, why? Looks like its coming from the side outlet


See if the side outlet needs a plug underneath to keep the grass inside the deck to be mulched. A lot of mowers have these plugs but this one might have not been installed.

Gas filter might not run properly and it must be replace. If it gets bad enough the lawn mower might not turn on and in worse case gasoline could start coming out the air pusher.
