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. I even tried it with starting fluid and had the same results.
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 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 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 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.
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!
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.
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.
Is the battery fully charged? Are the connections tight? Is the engine flooded? Is the air filter clogged? Is there proper fuel? Fuel filter?

Sometimes you have to disconnect and reconnect the switch, which is located under the seat.
If you are still having trouble you can call or visit you local Husqvarna dealer and I'm sure they will help you. You can also call Husqvarna and they will help you or tell you who to call or visit in your area.
There are several good suggestion on their web site and here is something on youtube that might help.
Your fuse is blown...should be located on the right side just behind the engine and clipped onto the steering tower lower steel section. Jumping it to the starter does apply power to the fuel shutoff solenoid therefore it will not start. Replace with the same amp rating...should be 15 amp (green or yellow)

I meant to say ...It does NOT provide power to the fuel shutoff solenoid when jumping direct to the starter :)

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.
Ours did that when we first got it. We had to take it back to Lowe's and they exchanged it (it had less than an hour on it). Guy at Lowe's later called us and said they found a piece hard plastic in the fuel line that had been there since it was in the factory. So, check your fuel line.
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
Sounds like you need to adjust valves!
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.
My Husqvarna won't start. It turns fine. It gets gas to the carb, but won't start. It fires up fine with a squirt of starting fluid, but dies without getting gas.
I have a Husqvarna yth1746 that I bought second hand. It will not start nor turn over. I have replaced the battery, coil, positive cable, and ignition switch. The fuse is good and the wires ohm out fine. I jumped the starter and fuel shutoff solenoid and the mower starts. However it doesn't even click over when I turn the key. I'd really like to get a step by step on what to check. I've been told that it could be the switch for the clutch, seat, or the neutral position switch. Any help I can get would be appreciated.
My Husqvarna riding mower won't start unless I add starting fluid into it every time. Any idea what I need to check or clean to fix this? I just need a starting point.
I was running my Husqvarna lgt2554 and I heard a clicking noise so I put carburetor cleaner in it thinking it would be fine and it died this morning and it's not running. Will it dry up and start in a few days?
MY pz5426 Husqvarna has problems starting. When I turn the key 10 times it starts right up. The problem is it will not start all the time 1 out of 10 times I turn the key and nothing. I have replaced the starter, solenoid, and ignition. I even added a good heavy ground to the engine. I can hear the solenoid click, but will not engage the starter.
My Husqvarna 22v46 won't start. It makes a loud constant sound when I attempt to turn it on, but won't turn over or anything. Any suggestions?
My Husqvarna GTH2448T lawn tractor will not start. It turns over, but sounds like it is only firing on one piston (one lunger) chug-chug. I tried disconnecting the spark plug wires on both sides and it sounds the same. Any suggestions?
There is a switch under the seat that is a safety switch. It will only allow the tractor to start if someone is sitting on it. It has a sensor that can tell if weight is on the seat. It may be broken or disabled.
How long has it been since you used your mower? Has it been running this season? New or old fuel?
I would suggest you call your local dealer and ask someone in the service/repair shop to help you out with what problem is most common with this model.
This type of question in asked quite frequently on ThriftyFun so maybe you might read some past answers. The second link is to a download site for a manual for your mower that might have some help (check page #25).
I was putting my Husqvarna riding mower up, it started fine, but after about 20 seconds it totally shut down. I put a new solenoid on and checked the battery; it is good. What would it be?
If your lawn mower won't start it could be one of two reasons why.
First, your carburetor could be clogged from leaving gas in the mower for an extended period of time. If stored with fuel in the engine over time the ingredients in the fuel start to evaporate and leave behind a sticker, stickier substance. You will need to clean your carburetor with a carburetor cleaner. If this doesnt work, take apart your carburetor and clean it or replace the carburetor.
Second, you could have a problem with your spark plug. Check the spark plug for signs of wear or change the spark plug.
Mine did the same and it was only two weeks old. Husquvarna found a peice of plastic in the fuel line. They replaced the mower. Check the fuel line well.
My Husqvarna CZ4217 mower cable on the brake broke. Now the mower won't start. Is there a saftey that I can by pass so I can get it on a trailer to bring to the shop?

I have a Husqvarna YTH1842, it has been starting fine. But today when I turned it off to check the grass catcher and tried to start it again, it wouldn't start. I stopped several times and started it each time just fine. Now it turns over good but back fires and will not start.
I checked the plug and fuel filter, took the fuel filter off and blew through it and the gas line. I got bubbles in the tank, so that was good. I checked the air filter, have fresh gas in the tank, the plug was dry and looked good, but the gas filter was not full of fuel, should it be? I hope someone can help me with this.
Here are some common reasons why mowers wont start: I did some research on the web for you. One reason is that you do not have all the components to make it start. It takes only 3 things to make a gasoline engine operate properly:
Water in the gas tank! Look in the tank and see if you can see a bubble of water underneath the gas (gas floats on water).
Another thing to check is the shape of the spark plug.Is it corroded? Does it have too much of a gap between the electrodes?
Have you checked the oil? Make sure it's filled properly with the right weight oil.(usually 10w30 works,but look in the user manual,it will tell you what type your lawn mower uses.
Drain the old gas from last season and add fresh gas.The old gas can be added to your vehicles tank. If you have it over two thirds full the miniscule amount from the lawn mower will disperse and be burned off fine in your car. And after this season, buy and add a fuel stabilizer for the lawnmower so the problems don't repeat year after year.
As long as you are doing all this maintenance,check the blades for wear. If you know how to sharpen them,now's a good time,or buy a new blade and replace the old one.To sharpen an old lawnmower blade: Put it in a vise and use a large flat file and run it at the angle that's there already.File one side,then flip the blade in the vise and do the opposite side. To check for balance? Pound a nail into the side of your work bench and place the blade on it.If it hangs parallel to work bench you are done.If one side hangs lower than the other, you need to file the heavier side another time or two and recheck the blade's balance til it comes out even.
Another thing to try is spraying engine starter fluid into the spark plug hole,reinserting the plug and trying to crank the engine. Does it try to start and then die? Now you know the spark plug needs replaced or cleaned up and gapped correctly.
Also,clean the air filter if it's sponge or if it's paper replace it.Next,check the cable that operates the choke to make sure it's working correctly. Too loose and you won't get enough fuel in the carburetor, and the engine will run rough or not at all.If there's a primer button, make sure when its pressed that fuel enters the bowl of the carburetor, if it's a weak stream,then you may have a kink in the line or a blockage, or a hole. Remove the line and blow air through it to make sure it's clear and try it again.

I have replaced the battery and starter, but the motor turns over slowly like the battery is weak. If I pull out the plugs it turns faster. What else could be my problem?
I have a Husqvarna lth130 riding mower with a Kohler 13hp engine. It was running fine until yesterday, when I almost ran out of gas. I'm thinking the carb is clogged with gum and junk, but I am not too knowledgeable in this field. I also read about the low oil safety switch, where is that located? I have fresh gas, and gas is flowing all the way to the carb, but looking down into the air filter I don't see any gas in the bowl? Any suggestions on what I should do next? I would appreciate everyone's help! Thanks.
