While cutting the chainsaw bogs down and stops

While cutting the husqvarna chainsaw bogs down and stops turning the chain. The chain is sharp and it is oiling. If you take some of the pressure off the saw while cutting it will slowly idle back up to full speed. But as soon as you put it back in the log it stalls again. Also it has a new plug.

Check the air filter and the muffler if either are plugged up it will not run smooth. Carb hi and low screws are very sensitive so if you change them, only move them a little at a time.

Husqvarna Chainsaw Chain stopped turning

Have you take the chain brake off..? This is a band which grips the clutch drum and must be disengaged before use.

Check chain tension, this shouldn't be too tight.

Did you also put chain oil in the oil tank.?

My Husqvarna 350 bogs down and is not turning the chain.

something is pinching the chain when you have the side cover on. either the bar isn't sitting flush to the saw or you don't have the chain in the sprocket correctly and that is causing it to bind

Will not cut blade stops with very little pressure when cutting. chain is engaged correctly on sprocket

Check the chain is travelling in the right direction, the teeth are sharp and there isn't too much tension on the chain restricting its movement.

Hi, my name is chris and i own a 460 rancher. just today the saw started to bog down when a load was added to it. seems to run at max rpm with no load however once touching the wood it will start to bog...

Hi Chris,
Check the air filter is clean and the choke plate is working ok.
Ensure the chain is sharp.
Check the chain isn't damaged and dragging in the guide bar.
A blocked muffler/silencer can cause loss of power.
Try screwing the "H" mixture adjustment screw in with the engine running at full power to reduce the richness of the mixture. Do this 1/4 turn at a time. Ensure you count the number of turns so you can get back to where you started.

Throttle Adjustment Hi/Lo idle Calibration

it could be the air to fule mix wrong but if it runs ok i would take a good look at the chain teeth if there even a little bit blunt take a file to the chain and tuch them up,,,,a blunt chain is very power sucking,,pluss you need to pull the chain through the wood,, a sharp chain dont need to be pulled it will cut well just under its own whaite

I have a Husqvarna 55 and it will cut but not great. The chain will stop and the engine will bog even on full throttle. Is it the clutch?

Is your chain sharp? Sometimes you hit stuff in wood without realizing it and it dulls your chain, dirt, nails, trash, it's all bad for the chain. If you aren't getting enough oil on your chain while cutting it will also shorten the life of your chain dramatically.

When cutting with my husky 440 16'' the chain catches or stops

It's hard to say. 41CCs should handle a 16" chain reasonably well.
  1. What are you cutting? Hard woods oak and maple are more difficult than pine.
  2. Are you digging in the dogs and trying to force the saw through the wood? Let the saw determine how fast it wants to cut, I rarely engage the dogs on my 359, I let the weight of the saw work for me.
  3. How sharp is your chain? Have the rakers been filed to low?
  4. Is the saw bogging down at speed before contacting the wood?
  5. Your saw was set extremely lean to meet EPA requirements. It is fitted with adjustment limiters also mandated by the EPA. To lean can impact how it performs.
All of these and few not coming to mind effect how fast the saw cuts. This isn't the answer you wanted but it is honest. We would have to see you cut and examine your saw to provide anything better. HTH

There are two idle screws one high, and one low. Your high adjustment idle screw needs to be adjusted.
