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.
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.

I have a Husqvarna 42" riding mower and the fly wheel keeps spinning; it won't start. Any suggestion? Please? Thank you.
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

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 was mowing and ran over an ant mound and the mower died. I turned everything off, made sure it was set just like it was when I got on that morning. It does nothing, not even a sound.
The lights work. When I put the blades in the on position and try to start, it clocks like it is telling me the blades are active. That is the only sound I get from the mower.My zero turn Husqvarna rz1306 will not start. I have put in a new plug, cleaned the magneto, added new gas, and cleaned the carb. It turns over and over. It appears to not be getting gas in the carb, but still won't start even with starter fluid.
Please help.
I have a Husqvarna pz5426 riding mower. The main fuse broke off (deteriorated looking). How can I get the rest of it out, or am I gonna have to take that 3 fuse box out and replace?
Also there is another place for a fuse right beside it, however it is not labeled. 25 p wiggles. Is it an auxiliary main?It has a fully charged battery. The engine will not turn over and acts like it is locked up. The engine will turn a small amount, but not a complete rotation. Once in a while I can turn the key on and off in such a way that the engine "bounces" and starts, but it has quit doing that now. The only way I can start it now is to remove the left plug and let the motor spin a few rotations (spins freely with one plug removed) replace the plug and it starts right up and seems to run fine.
After I have mowed for an hour or so it seems to lose power, but still mows. If I drop RPM to an idle it pops a bit and if I pull the left plug wire there is no effect. (Plug not firing at idle). If I throttle up the cylinder it fires OK under load. Last year I had the dreaded bent pushrod thing and replaced both heads. I am wondering if one of the heads I bought on (eBay) was bad.
I have a year old Husqvarna rider. It has fresh fuel, but every time I start it I have to spray starter fluid in the carb to get it to start. After running it starts no problem. Just on cold starts it has done this every time, but once since new.
I have a Husvarna YTH22V46. I tried to start it and it clicks. I had the battery checked and it was good. The water is full in the battery. The blade disengaged and the pedal pushed in and lever to choke. I could disconnect the battery completely and re-connect and it would start. I could mow without a problem and then finish and a day or so later, the same issue.
I've had it for 6 years and know the basics, but this one stumps me. I checked the connection under the hood and it is connected. It will click which the manual says means the solenoid is good. Any ideas or is it time to take it to a professional that can find the issue? Thanks for any help.
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:
Fuel
Fire
Compression
Answer
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.
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.
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.
