two things could be happening.......first is vapor lock......make sure you breather tube is clear and working........next is ....it could have a bad ignition coil on it.....after the coil gets hot the spark can become irratic or just not work any more.....

SOURCE: Husqvarna LGT2654 with Briggs & Stratton Intek Engine won't start

If the fuel line is dry after the fuel pump its usally the diaphram thats stuffed does it have a fuel tap in place? is it off? also i know with nem mowers just been come over from freight the fuel filter is full of oil for the first start up as the valves need lubrication first startup... take the fuel line off from the carb just have it hanging down for a start, then crank the mower over, you should then have fuel coming out of fuel line by then... see if that helps jay QLD AUS

SOURCE: Husqvarna z5426 running rich and fouling plugs

Sounds like a fouled needle seat, or the float bowl is failing.

Start with:

Pulling your Carb, and cleaning it out. COMPLETELY.
A ton of people think "a shot of carb cleaner, and a gasket kit" is a carb fix. It is NOT, and WILL NOT fix a carb, if the problem isn't gaskets, and shots of cleaner!

Meaning, if she is running too rich, then too much fuel (as you said), and fouling plugs, remember there are only a VERY few things in the carb anyway as it is.

1. Needle Seat
2. Fuel Float Bowl
3. Butterflies
4. Fuel Ports
5. Air Ports
6. Gaskets/Diaphragms.

My advice: (This assumes you HAVE NOT ADJUSTED YOUR CARB OUT OF DEFAULT!)

Pull the carb (Carefully!) and tear it COMPLETELY down (Carefully!). Note where stuff went, take your time, be patient.

When you have everything but the butterfly plates out, run some Gum-Out through each and every port, after you made sure to pull the Float Bowl, and the Needle Valve (and remembered how they went back in there!). Take some compressed air, and follow through (CAREFULLY!) on each and every port. Clean the very TIP of the Needle Valve. Shake your plastic Float Bowl. Does it have liquid inside? She has a hole in her. REPLACE!

If not, then this exercise was cleaning crud/residue that is ALWAYS building up inside carbs in 2/4-stroke engines world wide, every day. NOW do a "carb gasket rebuild".

Note: Remember that sometimes, crud/junk is testy, and stubborn as a mule to get out. Double check any screens above/below your Needle Seat and Valve. Remember that Needle Valves come with solid tips, and some with rubber tips. Regardless, be careful, and clean thoroughly! A Needle Seat that isn't getting closed, is a Needle Valve that is letting WAY too much fuel in!

SOURCE: spitting and sputtering

mine did the same, I found out that the high speed jet was clogged, I pulled the fuel line off the filtor(going to the carb), stuck the line into a mixture of half gas half carb cleaner, I fanned it up and in 2 or 3 minutes it started running well, hope this helps.

I have been using my Husqvarna yth2348all summer now it wont start. There is spark and fuel going to carb. There was a huge mouse nest. Checked carb bowl it was clean. Any suggestions?


Hi Todd:
Here's a couple of things I would do.
1) See if there is a drain plug on the carb, If there is, drain it so that you will be getting fresh fuel into it.
2) Remove the air filter cover, then remove the air filter make sure it is clean. Replace if it's really bad.
3) Squirt a bit of fresh gas into the throat of the carb, put the air filter back in place, and try to start. Usually it will be good and run. If it doesn't, youre not getting spark. If it runs a bit and then dies, you're not getting gas. Try the prime trick a few times. If it still won't keep running you'll need to take the carb apart and clean it.

Was using saw ran fine stopped and returned next day will not start fuel fine new plug filterers gas and air still wont start took to local chain saw repair shop they said that because it had water in gas...


check the carburetor. If you have a stiff diaphragm then it won't run.
I have seen them that behave just like that. They will run fine, turn it off for a few minutes then they won't restart. WD40 isn't going to get it to run either, try a small amount of mixed gas right into the carb. It should run for a minute until the gas you put in runs out then die. If it doesn't run then you have a bigger problem

Husqvarna weed eater starts , but blows alot of smoke & then stalls out


Rod, Carb. may need adjusted, try loosening gas cap and start to see if cap vent plugged, there is a in tank fuel filter that you could fish out and remove to see if it is plugged. If still not running remove muffler and clean spark arrester screen, if screen plugged the trimmer will do this.
Check the attached links,instruction and guides, Good luck

Husqvarna Model#136 Serial#20033000836 chainsaw. When I first start my chainsaw, it starts on the first or second pull and it will run perfect until it runs out of gas. I have to wait until it cools...


Your fuel octane is GREAT ! Good to hear you are using fresh fuel. Make sure to use Husqvarna HP oil. It makes a difference of the heat generated by the engine.
1) If you can: Do not run the saw dry when cutting. As soon as you have the indication that it is almost dry, stop. Remove the fuel cap to remove pressure in the tank. Allow a 5 minute cool down before refueling.
2) I see your saw is a 2003, you may have debris under the flywheel shrouding restricting air flow: remove the recoil assembly and flywheel cover/shroud under the recoil. (if it has one)
Check to see if debris has gathered around cylinder fins.
Clean with compressed air. The ability for the flywheel to breath means more air to cool the cylinder and lower the overall operating temperature of the engine.
3) Make sure the air filter is clean and area is free of debris.
* Each item may be small, but each one builds on the operating temperature.

Problem keeping engine running on Husqvarna 22HP VT riding mower


Take the fuel bowl off and clean it real good as well clean the fuel jet. It may be the bolt that holds the fuel bowl on. I am not sure. I use my air compressor to blow it out also get a real fine wire and put through the fine hole may help. It does not take very much dirt to make an engine not run right. I repair a lot that way that is not running properly.

Toro SR4 Running problem when hot


It can be quite a things - a blocked air filter or a blocked exhaust. To clean the exhaust, unbolt it from the manifold, hold it vertical and hit on the side until no more soot comes out. Changing the air filter should be pretty straightforward. If the spark plug bottom end is black then you have the fuel mixture too rich and you should lessen the flow of fuel.
