My Husqvarna will only stay running with the choke in and even then it will only run for a short time?

usually this sign needs fuel

Could be a couple of things. First guess is the carburetor is bad. Because when the saw goes from the choke circuit to run it dies.

Choke open is the run correct position. If you close the choke, you cut of the air flow to carburetor.

More than likely a fueling issue, wrong fuel air mix or air leak somewhere

Take apart the fueling system and carb. Something is blocking or gummed up. One thing that sometimes works is to remove air filter, rev the unit up, and place hand fully over the intake, and remove before unit stalls. This sometimes will clear the blockage.

Take the saw back for warranty service. We have a Husky #435 that had starting problems when new last year--warranty service replaced the ignition module the first trip, then a little later, they replaced the carburetor--it has worked very well since. I suspect that Husqvarna has had problems with our ethanol blended fuels. Hope this helps!

if it is already running and you "engage" the choke, you will flood the engine with too much gas and it will sputter and die. the only time you engage the choke is to start the engine when it is cold. if the mower dies when you remove jumper cables, and you leave the choke alone, you need to have someone look at your charging system.

Hi,
If it is only running high at full choke - then it is not getting enough fuel.
You've cleaned out the whole thing - so it's not air that's the problem. It's running - so it's not a spark problem - it's a fuel problem.

If you have a fuel filter - change it out or clean it properly. If the fuel line is clear, then you need to adjust the running setting of the carb - there are usually 2 setting knobs -one for idle - one for running / mix.
You need it running richer till you get it going - then trim it back to stop it smoking and get a good rev.

check your fuel pump to see if working,, then clean or replace carb,, and do tune up on it,,, hope this help you,, good luck

ok,  The choke is used to change the air/fuel mixture by "choking" off the air that goes to the carburator.  The choke is only used to get the motor running in cold temperatures.  Once the motor is started, the choke must be opened or the motor will flood and stall when you open the throttle.    I hope this solves your problem.  Best wishes, Michael Mittelsdorf
