You start at 1-1/2 turns from seating and adjust from there for best mixtures.

SOURCE: on the husqvarna se266 carborater, what is the low

Initial setting for a Husqvarna; "H" and "L" screws at 1 turn CCW form lightly seated. Then tune for performance like this:

CW is leaner; to lean will destroy the saw. If over tightened closed (CW) the adjustment screw faces are easily marred; marred adjustments are difficult to impossible to set properly.
Clean the air filter; adjusting with a dirty filter can cause a run lean condition once cleaned and the saw run.

Where can i find a tool to adjust the high and low on the carb of a model 141 husqvarna chain saw


Stihl have a small orange screw driver- a tuning screw driver, it has an arrow on the end to show how many turns you have done when tuning your saw

Keeps cutting out


More than likely its a tuning issue, needles and jets can get gummed up if the engine has sat round for a while with fuel in it. The fuel tends to evaporate and leave behind the 2 stroke oil residue.
Unscrew both H and L tuning screws (not all the way out, just a few turns) You may need to purchase the tuning screwdriver as Husqvarna blowers are fitted with Walbro carbs that have tooth edged tuning screws.
Once you have unwound them a few turns, Pull the blower over (a few times. It may fire up, it may not) Then to reset them to factory settings Screw them both all the way in and then turn them each out anticlockwise 2 & 1/2 turns.
If its still not running right it may need more investigation but it definately sounds like a fueling problem.

My Husqvarna 335LS runs rough and will not run at full speed


Check the exhaust, the muffler contains a gauze which can deteriorate and restrict gas flow through the exhaust. Have you stripped the carb down and checked the diaphrams/gaskets, removed high and low tuning screws, cleaned and reset to standard settings.?

Hi. I inherited a 1998 Husqvarna 265 rx. Got new plug and new fuel and it fires ok. Wouldn't stop so I added a washer under the 'earth' screw and it now stops. Problem is poor acceleration


To set the throttle, start by slackening the cross head screw securing the cable in the handle and pull completly out, now slacked the three allen headed screws securing the handle, twist the handle to the best position for your use ( at full throttle your thumb should not be straining ) now slacken the lower cross head screw and turn the silver clamp to tention the spring underneath, when correctly adjusted the throttle trigger should spring back to the idle position readily, now re fit the cable up through the clamp, turn the cable so as it is just about to open the carb throttle spindle, lock the cross head screw and test to make sure you are getting full throttle, if not slacken the screw and turn cable a little more.

How do you set the mixture screws


I'd start at 1.5 turns CCW from lightly seated. Then tune for performance. It is probably fitted with tamper resistant fittings mandated by the EPA. I contact my local Stihl dealer when my saw needs adjustment. HTH

What is fuel air mixture screw settings on husqvarna 371k


I will admit that I am not particularly familiar with this manufacturers specific models, but I will state that for most small 2 stoke motors I seem to find that 1.5 turns out seems to be a great place to start for both the high and low speed mixture screws. From there it is all fine tuning to get the most out of the engine while still keeping it rich enough to prevent damage.
