I have a Husqvarna YTH 2348 mower that has spark, gas, and new gapped plugs. It fires once or twice when starting, but that is all.
Did you leave gas in your mower last year? If so, it is not unusual for old gas to "gum" up and this will cause your mower to act the way you describe.
Just in case you no longer have the manual, you can check it out here: Troubleshooting starts on page 25:
My son says you may have to siphon out the remaining fuel, add fresh fuel and try to start the unit. Maybe you could add a fuel stabilizer/Synthetic Fuel Additive at that time and always add something like Sta Bil when it will be weeks or months between uses. You might ask for help at an auto parts store as they sell all of these products.

My Husqvarna was running and cutting grass then it started running rough. I shut off the clutch to the blades and tried to reengage the clutch, nothing.I then shut off the engine, and now there is nothing, nNo click, no pop, nothing! What the hell happened?
Sounds like your carburetor has blown. You may also have a starter issue. With your mower running rough and now nothing, it was giving you the last clue before turning off. Hopefully after the carburetor replacement, there wouldn't be a battery issue ,because the battery may have kept this mower going longer with failing parts. Have battery tested, there are many places that do that for free. This makes sure that when parts are replaced, that the battery will be strong enough.
If the lawnmower was running rough and you heard some noise from the engine as you were cutting the grass it sounds like the engine has seized up and is no longer cranking over. You could have blown a gasket in the engine which caused it to either leak oil or get oil in the crankshaft of the engine. You will need to take this apart and make sure that the motor of the mower has not seized up and frozen. If you can no longer crank a mower this is normally what has happened to the engine.
Actually, this could be due to a maintenance issue but probably has to do with the carburetor.
If you are mechanically inclined you may be able to take your mower apart and check for problems.
Just be sure you have clean (preferably new) air filter/gas filter, spark plug before you retry the engine as all of these items (and more) could cause other problems.
If possible, I would suggest you take it by one of your local auto parts stores and ask someone to check it out for you. They are usually very accommodating and some may have meters for checking almost everything.
Lawn mower shops can do this also but they'll be more interested in keeping the mower for repairs than your auto shop.
You can also post your question on some of the repair forums and they'll know what questions to ask to help you figure out what needs to be done. You may have to join the group before you can post and some take a little figuring out on how to post.
You'll need your model number also.
There are also lots of YouTube videos on how to repair almost everything on a mower.
My Husqvarna lawn mower won't start. I have now replaced the battery and solenoid and 20 amp fuse and still nothing when key is turned on. It shut off yesterday when my wife was cutting the grass and now is silent as a sleeping newborn baby when the key is turned on.
I also have a husqvarna. Make sure the mower is disengaged, and that you don't have it in reverse.
My riding mower won't start. The plugs are good, fuel filter good, and it is getting fuel, but acts like it floods.
It sounds like you have an issue with the choke on the mower and it is flooding the carburetor. You carburetor is getting too much gas right now and that is why it is flooding. Check the fuel value and the gas filter on the mower and see if you can change these or clean them.
My mower won't start. It has new fuel and a new filter. Gas does not pass through the fuel pump. There is a spark from the spark plugs. I tried spraying starting fluid into the carb, it still does not try to start. I am stumped.

I just had the same problem. My neighbor figured out at the top of the gas cap there is a hole. It was plugged. Worked great after that.
My battery is new; it is getting plenty of juice. When I turn the key, it tries to start, then there is a loud knocking sound and whining sound from the battery area. It has new gas and a clean air filter. Several previous times it was as if it was dragging, but it finally started.It caught fire at the fuel cut off and I had to replace the ignition harness. I'm thinking it's the starter. What do you think? The fire and harness replacement was about 4 months ago.
This could be your starter or even your carburetor. You should pull the starter first and take it to a lawnmower shop and have it tested. They have a machine they can test this on.
I bought a brand new Husqvarna riding mower. I used it for a month and then stored it in the storage for the winter. Now it won't start. So I used a jumper cable and it started fine, but once I turn it off it won't start unless I use the jumper cable again!Any idea what's wrong with it?
If your battery is good, then it is likely a failed voltage regulator. Take your battery to advance auto parts once charged fully. They will test it for free usually. (At least in Georgia.)
I have an YTH 1842 Husqvarna. When I go to engage the mower every once in awhile it doesn't turn on.
Have you tried reducing keys weight on your keychain....it can make the starter stay engaged or run the starter down. You might have to disengage the blade before it will start if it is an older version.
This was from what my husband advised me when I asked him.
I have a Husqvarna 42" riding mower and the fly wheel keeps spinning; it won't start. Any suggestion? Please? Thank you.
Woodruff key is broken, or bottom of carburetor needs work.
YTH20V46 Husqvarna lawn tractor that won't start. I've checked the fuel, the battery, fuse, and replaced the solenoid. When I turn the key nothing, but the hour display comes on.
Apparently it can be a common problem.
This is normally associated with the lack of incoming air or fuel not reaching the engine. Check to ensure that there is fresh, clean fuel in the fuel tank. Also check the fuel filter, because a clogged fuel filter will prevent the engine from obtaining adequate fuel supply
But it sounds like you already did that, so a next guess is check the carburetor, which can also fail
I have a Husqvarna riding lawn mower. I have a new battery, but it wouldn't engage. I tested it by jump starting. It will run, but is not firing up.
You may need a new starter or cam shaft.
My Husqvarna riding mower turns engine good, but it does not start every time. I try later and it starts and runs great.I changed the fuel filter and use new clean fuel every time. It also has a new air filter and new spark plug.
I have a Husqvarna rider that won't turn over with the plug in. It turns freely without it.
By BILLY R SEXTON from Huntsville, AL
Plug is either too long, or something is going on with the head of the piston, causing it to seize.
Try switching out your carb, or you can rebuild it. Sounds like your needle is sticking.
Fuel cut off switch was answer for me
I have a Husqvarna yth2248 mower. It won't start using the key. I can crank it by using a piece of wire and touching the 2 terminals on the starter, but it only cranks. I can keep it running by spraying starter fluid, but it cuts off when I stop.I can raise and lower the rpm while using starter fluid. Any ideas on what the problem is? I did spray the mower down with a water hose prior to all of this. It did run 3 months ago.
I have an LTH 130 Husqvarna riding lawn mower that won't start. It has clean fuel and new filters. I know the battery is bad, however if you take jumper cables and touch the starter it just sounds like it's starting, but won't catch.I am not sure what to do.
