I think the carb isn't pulling fuel in. That's why they arent able to keep it running with out using the choke. I'm having the same problem with mine.

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

    This is what you need to do.  First leave the choke in, prime the saw (if there is a priming pump), switch on, try to start with two or three pulls, if it starts, it should operate normally.  If not,  leave the switch on, pull out the choke, start the saw,  let it idle for about 10 seconds and push in the choke.  It should work fine.  If the saw has no priming pump, pull the choke out and try starting it.  After about 10 seconds push in the choke and you can use the saw.  
        If after starting, you push in the choke and the saw quits, next time only push in the choke half way in.  The choke only closes a flap to choke of air for the air mixture.  So in colder temperatures you may need to pull out the choke more.  On some saws the choke provide more choke than you need (or if its warm) so you will need to use more fine adjustment when using the choke.  
         In general, the choke is used only for starting.  Once the motor is started, it should be pushed in (disengaged).  So if the choke is too coarse an adjustment and the saw wont continue running no matter how you set it...you may need to have the air/fuel mixture on the carburator adjusted.  
       Good luck and I hope this will Fixya!  Michael

Most likely the battery isn't holding enough charge which is why the PTO won't engage.
Likely you have air in the fuel line/fuel filter which lets it run for awhile then it fuel starves.

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.

Husqvarna 55 chainsaw won't stay running.


It has a crack in the fuel line between the body and the tank. The crack lets air in the line. Replace the line.
