Hi everybody,I have a question about my almost new 241 cm.The saw was running fine,no problems.About 2 weeks ago I cleaned the air filter for the first time.Now the saw feels sluggish and wont idle.The problem started about 5 minutes after I had cleaned the filter.Saw is under warranty,so it will be made right.But im just curious what would cause this?Thanks for any help.By the way,the spark arrestor is clean and the plug looks new.

Do you have the filter on incorrectly? Blocking the air it should be getting.
Theres really only one way it can go.It "twist" on.
If junk went into the carb, it should go straight into the engine. It can't really get into the internals of the carb in that method.

I don't know that model. However, I assume that you had to remove some plastic covers to actually access the filter. If so, then my money would on the possibility that you've accidentally trapped a wire or pipe etc. when reinstalling the covers.
If it were my saw, I'd be inclined to remove the covers I took off to change the filter, blow the area clear with comp air. Check the whole surrounding area ensuring all pipes/wires are good. Perhaps then I'd remove the filter, and restart and see if the problem persists.
Also is there a winter/summer air position switch that you might have upset?
Don't run a saw in the summer on the winter position!

Thanks for all the replies.Im taking the saw to the dealer in the morning .My bet is on the electronic controlled carb,something is out of whack.I will let you all know what the problem was as soon as I find out.Hope the dealer works fast,I really like this little saw.And I'm only left with an 031 and a SXL Homelite.

Just curious, what did you "clean" the airfilter with? No insult intended but if you used a chemical it could have ruined the filter in a manner that wont allow air to pass through easily. Pull the top cover and take the filter off and try to start it and see what happens. It's worth a shot anyway.

Thanks for the reply.I just tapped the filter on my truck bed and most of the dirt came out fine.Really wasnt very dirty,but needed cleaned.I tried no filter,with no luck.Thanks again
Thanks a bushel for all the info,Im gonna try the recalibration first thing in the morning.I had a feeling the carb compensated for the dirty filter,and maybe couldnt reset itself.I will keep you informed,and thanks again.

This is a prime example of why I have no intention of having a saw with an electronically controlled carb.
Hope you get it straightened out.

One day they all will be electronic and we'll just have to keep running the old beast and killing our back lol

any luck
Turns out it was the solenoid valve in/on the carb.Good thing it was under warranty ,that tiny part would have cost $43.49.She is running like new again .I tried to recalibrate first tho.Thanks again everybody,maybe this info will prove useful to someone else someday.
