Why won't my Husqvarna riding mower start?

I have the same mower. It worked great the first season and now I have to manually open the throttle while cranking to get it to start. I just open the engine cover and place the throttle lever to the full-choke position and then press the throttle open at the carburetor with my left hand while turning the key with my right hand. Fires up immediately.

I imagine that this could be corrected with an adjustment, but I need to open the cover to check oil level and it's very simple to do so I don't mind.

You will see where to place you finger if you move the throttle lever from one extreme to the other while watching the carburetor at the same time. Just press the little lever the rest of the way towards open and crank it up.

Good luck. I hope this helps.

The first thing that I would check would be the fuel shut off solenoid on the carburetor. You should be able to here it click when the key is turned to the run position.

gas goes bad after sitting for awhile.

more than likely the carburetor is gummed up and needs to be cleaned,

sometimes you can get lucky and clean it by buying carb clearer in an aerosol can and spraying it in the carburetor.

but more than likely it will need to be taken apart and cleaned, easy process you can do yourself (you would have done this already if you knew what you were doing) so either find a friend/neighbor who is good with small engines to take a look at it, or take it to a small engine shop.

in the future, when you are done using it for the season.

let it run itself out of fuel (best option)

or buy a fuel additive (like staybill) to help extend the life of gas. you would pour this into the gas tank at the end of the season & let the machine run for awhile with it in the tank.

Also when buying gas for any small engine try to buy non-ethanol gasoline, can be hard to find & maybe a bit more expensive per gallon but will save you headaches in the future.

I have a similar problem with mine Briggs and Stratton LM. I come back after not using it for a while and it fails to start. When I look at the fuel tank it appears to have a decent amount of petrol left but it will not start unless I completely fill the tank to the top. On mine it would appear that the outlet pipe feed from the tank is about 1/2 the way up from the bottom of the tank and so even though there appears to be lots of petrol there it is not enough.
