Question about Husqvarna Garden

1 Answer

Brand new Husqvarna 340e chain saw dies after 10 to 20 minutes.

Saw never worked right. Found that by opening the gas cap for a second when it sounded like stalling the saw would run for another 10 to 20 minutes. I can keep it running in this fashion for the entire tank of gas.

    The fuel tank vent was new and working fine. I removed the vent completely and tried to tip the saw but no gas came out of the hole. I blew air into the vent hole, but no air movement in the tank. It looks like the gas tank has a problem.

    Thanks for your help!

    Saw only runs when tank is at least 90% full and won't run at all when on side

Husqvarna 450 e-series 18" Chain Saw will not

Is this machine mechanically sound, remove the muffler and take a look at the piston through the open exhaust port, any signs of scuffinf or damage to the piston skirt and the saw will have to come apart for further investigation.

My husqvarna chain saw will start fine and run good and cut good for a few minutes then it will start running fast then slow down run fast slow down it will do that 3 or 4 times then cut off any idea...

It certainly sounds fuel related, remove the fuel hose from the fuel tank and replace the filter on the end, try the machine again, if it is no better it could well be an issue with the fuel tank breather, to test this run the saw until the problem starts to occur, slacken the fuel cap enough to allow air into the tank, if the machine picks up and runs well you will need to replace the tank breather, let us know if this works and i will will go through how to change the breather.

I have the same problem with my 350 Husqvarna chain saw. I took the saw to a licensed Husqvarna Dealer. The dealer said that there was noting wrong with the saw. The dealer did clean the carb. I brought...

The temperature is not that different. Is there a fair change in altitude between the dealer and where you live? The jet screws have 'D' heads to prevent owner tampering--how did you adjust them? You need to allow the engine to warm up before pulling the throttle. Make sure the fuel mix is fresh and mixed 50:1 with synthetic chain saw oil--be sure to shake the container thoroughly just before filling the tank each time to prevent oil starvation. It has to be the manufacturer's problem because it is under warranty. It sounds like the jet screws are set fairly lean. Ask the dealer if you can buy the special 'D' head screwdriver to make your own adjustments. Hope this helps!

Starts on choke, dies when taken off...

A brand new saw should still be under warranty! Let dealer service take care of it. The fuel tank filter may have sealed itself. Fish it out of the fuel tank with a hooked wire to check and/or replace it. The cap seal should be a rubber 'O' ring around the cap body. The vent should be a beaded bronze plug that is cast into the plastic tank. Try blowing out any sawdust with compressed air through the starter grill which should unblock the vent. The jet needles have 'D' shaped heads that are supposed to prevent owner tampering, and require a special D-recess screwdriver to adjust. Only authorized dealers possess them. (I made my own tool)

Saw stops when i give it gas.

  • plugged fuel filter
  • cracked/loose fuel line allowing air (instead of fuel) into the carburetor.

Chain saw emitted sparks and now does not start.


When the engine get warm and die(I suppose)check the spark at the sparkplug.You can let the saw run until it ran out of gas and you will not distroy the engine.Change the sparkplug.

Chainsaw kills when I press the throttle

My 372 xp did that and when I talked to the repair shop they even showed me. There is a fiberglass gasket that is used to mount the carburetor to the engine. I have no idea on how this happens, but I saw it with my own eyes. The gasket had actually folded over. They replaced it with a rubber one and have had no problem since. The saw was hard to start, would run as long as I didn't try to cut anything and when I did it would open up and then die. I could be giving wrong information, but that sounds exactly like the problem I was having.
