This is not so easy to explain, this is an X Torque engine so the carb does not come off so easy, there are air tubes on the back of the carb, however, remove the air filter, remove the earth cut out wire and earth return wire from the red switch, they are just push on, there is a blue clip on the throttle shaft side of the carb, gently pull out and twist ( this holds the throttle push rod into the carb ), open the throttle trigger with your finger at the same time now remove the throttle push rod from the throttle shaft, once out of the carb pull the rod toward the front of the saw and out of the tank, now unscrew the four allen headed screws from the air filter housing, and remove, ease the carb up and away far enough to remove the fuel hose, now remove completely.

SOURCE: I have a husqvarna 455 rancher. It was working

Take it right back to repair shop and have them fix under their warranty.

It is possible the fuel hasn't got to the carbureator due to plugged fuel filter or fuel finder OR an air leak in the fuel hose.

SOURCE: Fuel Mixture Husqvarna 455 Rancher Chain Saw

Page 17 of your Operator's Manual says 50:1.


Fuel/Oil Mixture

  1. Use a quality 2 cycle oil and mix it to the OIL supplier's recommended ratio. Today I use Stihl 2 cycle oil mixed @ 50:1 in a Pioneer that I purchased new in 1980. There are no gouges or scratches on the piston or cylinder and I have no carbon build up on the piston top. The manual (on stone tablets) recommends 24:1. Over the years the mixture has leaned from 24:1 (Saw Recommendation) to 28:1 (Lawn boy mower recommendation) to 32:1 (Oil provider 8oz/2gal - used for many years) and finally the last 5 (±) years 50:1 (Stihl 2.6oz/1gal)
  2. Most gas in the US of A contains ethanol; not good with chainsaws. Mix what you expect to use within a few months. Anything over 6 months old use up in a 4 cycle engine. HTH

SOURCE: How do I replace chain on Husqvarna 455 rancher

Unlock the chain brake and remove the clutch cover. This should provide what you ask:

If you get stuck or need model specific instruction, there is very detailed illustrated instruction in your manual under "Fitting the bar and chain". The tool-less adjusters add needless layers of complexity IMO.

Why won't a husky 350 idle


You most likely have a fuel delivery issue. This could be anything from bad fuel lines, clogged fuel filter to a bad carburetor. Start with replacing the fuel lines. They most likely need replacing anyway. The fuel filter should also be replaced. Then if the problem is still around, you have carburetor issues. I don't recommend rebuilding, they are too cheap to rebuild. Buy a new one.

Husqvarna 455 rancher new filters /plug get spark wont start put gas in cylinder and wont start what am i missing


Check to see if there is a leak in the air purge bulb (primer bulb), sometimes they crack and allow air in and don't push the gas through properly. Here is the manual for your saw.
Cheers!

How do you change a fuel filter on a husquavarna 455 rancher


Hi Rick,

To change the fuel filter:

1. Drain the gas from the tank and run the saw until it is completely out of gas.
2. Remove the top cover. You might also have to remove the air filter.
3. Locate the fuel line from the tank to the carb. Detach the line from the carburetor.
4. Feed some of the line into the tank if you can. With pliers, pull filter far enough out of tank through the fill hole so you can get the filter and a little of the line.
5. Pull the filter off and replace with new one by twisting it onto the line.
6. With pliers, pull the line back to the carb from the top and reattach to the carb.

Hope this helps. If it does, I'd appreciate your vote. Thank,

My 455 rancher bogs down when i give it gas it's not even under a load new plug air filter, fuel filter, made carb adjustments like manual said running 93 octane gas.it,s still bogging


Make sure the chain break is releasing all the way. When the saw is not running release the chain break and make sure you can move the chain back and forth by hand. If you can there is a small fuel filter in the gas tank that should be replaced. Make sure the fuel lines are not spongy because they could collasp when the engine is running starving the carburetor for fuel.

I HAVE A HUSQVARNA MONDO LINE TRIMMER.WHERE DO THE FUEL LINES CONNECT.THE MACHINE HAS A WALBRO CARB.


For a machine with a remote primer bulb: The small diameter line out of fuel tank (has filter in-tank on end) connects directly to the side of the carburetor that has the fuel pump....that is the cover without the hole in it. Other larger diameter fuel line out of tank connects to the longer nipple on the external purge/primer bulb. The bulb "pulls" fresh fuel from the fuel tank to the carb and then out of the carb to itself, where it then "pushes" any air/old fuel back into the fuel tank. The remaining larger diameter fuel line in this setup goes from the metering chamber (has cover with writing on it and a vent-hole) side of the carburetor to the smaller nipple on the purge/primer bulb. Again, on the primer bulb, the longer nipple has a line going directly from it to the tank. This is the return line. The shorter nipple on the bub has a line from it going to the metering chamber side of the carb. For a machine with the purge/primer bulb on top of the carb: The small line from carb body to small hole in tank with filter. Larger diameter line goes from the bulb on the fuel pump side of the carb to the larger hole in the fuel tank where sometimes the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank. Otherwise, the line should enter the tank for about 1/2" or so.

I have a Husqvarna 455 about 2 years old. At about 1 year point it would no longer start using the primer pump button on the side when cold. If I take off the air cleaner and give it a a shot of gas down...


Your seeing the problem. Air in the fuel lines usually caused by a cracked fuel line or a pin hole in the primer bulb. Until you can stop the air bubbles by either replacing the actual primer bulb or fuel lines your always going to have the hard to start problem. This can also cause the engine to run lean at high RPM settings and eventually burn a hole in the piston. You should repair the fuel problem ASAP. If you do not find any fuel line / primer bulb problems then it is time to start looking at the carb diaphram.

My Husqvarna 128LD primer bulb will not fill with gas


The primer bulb does not have to be full of fuel for the carburetor and trimmer to operate correctly. The actual function of the purge/primer bulb is to help pull fresh fuel into the carburetor while at the same time, push old fuel/air out of the carb and back to the fuel tank. You may have bad check valves in the primer base assembly but, the machine can even operate if the bulb is only even 1/2 full or so...Make sure the fuel is moving in only one direction during and after the bulb is pushed and released. If it's not....bad check valves. These valves are very small and fragile and easily damaged by strong solvents, high PSI compressed air...and carburetor bath type cleaners. You didn't state whether the machine will start, run, what have you. Repost if needed. Please vote on this solution.

Wont start put new plug and new gas.


Did you check for blue, snappy spark at the plug (gapped at 0.020") when you replaced it? If ok, put some fuel mix into the plug hole and try for start--it should pop several times. If ok, check the fuel filter, air filter, and muffler for plugging. Check the fuel lines for any decay or other damage. Make sure the carburetor fasteners are tight. Does the primer bulb pull fuel into itself after several pumps? If nothing, remove the fuel line from the carburetor that has the filter inside the tank and place it on the primer port that has the line coming from the carburetor. Try to pump fuel again--if successful, then remove the carburetor from the engine and clean it inside and out with spray carburetor cleaner. Check the lower chamber diaphragm for flexibility and no cracks or holes. There is also a small mid-body filter that can easily plug with stale fuel mix. Hope some of this helps!

  • The hose in the tank with the filter on the free end connects directly to the carburetor input connection.
  • If the saw is equipped with a primer bulb, the output line from the carburetor connects to the suction side of the primer (once the bulb is collapsed it draws fuel from the tank through the carburetor to refill the bulb as it inflates).
  • The pressure side of the primer returns displaced fuel to the tank as it is depressed.
Take lots of notes and a few digital photographs will help with reassembly. HTH
