Make sure you are using the correct fuel mix.

Check fuel tank vent, prone to blocking an can effect the performance
Clean air filter, check Spark plug.

SOURCE: 455 rancher chainsaw does not pump oil to the chain

Check your operators manual carefully many new Huskys have a 3 position oiler with 1 being the least and 3 the most. It is easy to turn beyond the detents and once done oiler problems abound.

Is this a new saw? Still under warrenty? If yes the dealer where
you purchased should be willing to verify proper oiler operation at no cost. If purchased from a big box store or on line all bets are off.

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: magneto to flywheel gap for Husqvarna 455 Chain Saw

Ignition module gap
Place a business or index card between the fly wheel and coil, rotate until the magnetic attraction pulls everything tight together. Tighten the coil screws, rotate the flywheel until the attraction eases and remove the card. Ensure nothing contacts when flywheel is rotated.

SOURCE: i have a husky 455 rancher.never had a problem

When this has happened to me, it turned out to be a hole or crack in the fuel line. At the higher revs, more fuel is needed. The added "suction" for the higher demand pulls air into the line and the unit does not have enough fuel to run. Check for that first and also the fuel filter inside the tank. The filter might be clogged as well.

Keep us posted,
Dan

My 455 revs up and down while giving it thortle


Check the fuel tank vent, ive had 455 and a 450 rancher in for repair that have had the same symptoms. Sometimes it can be the breather pipe that has come off the carb, ive had that happen on a 395xp.

The vents are simple to change and it sorted out the problem on both saws. 1 was simple to spot as it leaked fuel when laying on its side.

50to 60 compression on a husqavarna 455 rancher chain saw. Ring job and how hard?


455 is an X Torq engine, this means it runs very cool on the inlet side of the piston, they are quite prone to gumming the ring in if they have been used on a heavy two stroke mix, due to the designit is a full machine strip down to get to the piston, skilled man 3 hours to strip and rebuild.

Before you do anything else i think you need to check the engine is mechanically sound, remove the muffler, take a look at the piston skirt through the open port, any signs of scuffing on the piston and it will require removing the cylinder to assess the damage, they are x torq engines, due to the way the air ports work they are quite prone to carboning in the piston rings, make sure it has plenty of compression.

My Husqvarna 455 starts great and sounds great without pressure but when you put the saw under pressure of cutting it bogs down and runs up and down. I am not sure the problem. I have changed spark plug,...


If you haven't done so already I would run some spray carb cleaner through it. If the idle speed is okay then I would adjust high and low screws going very slowly about 1/16 of a turn at a time and run engine up and down after each adjustment. I would remove the muffler and clean the spark arresstor screen to get all the carbon deposits out of it.Carb. cleaner and a medium stiff wire brush work well for this. I would also check the vent in the gas cap to make sure it is open. I also use a product called sea foam in all my engines.For my chain saws I mix 5-6 ounces with 2 1/4 gallon of gas.It really does a good job of keeping everything internally clean. Hope this helps you. Thanks.

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.

Does it have plenty of compression, they are very prone to gummimg the piston ring in if you have been useing a large fuel oil mix.

I have a 09 455 rancher that will start with choke on . Idles with choke off but bogs when throttled up. I believe the bottom carb gasket is leaking. Parts houses say call for carb parts.


If gas is leaking from the carb, can you see if it is a damaged fuel line with a leak or coming from the carb itself. If it is the carb tighten the screws on the carb itself. If neither one is the problem you probably do need a carb kit installed. Hope this is helpful. Best regards and good luck.
