Stihl MS261 slow to rev down - common problem?

[morten]

I'm getting increasingly annoyed about a single aspect of my 4 month old MS 261.

 

It seems very slow to rev down, when you let go of the throttle. The consequence is that the chain takes "forever" to stop. I have adjusted the idle speed down as far as it can go without stalling, but it didn't fix the problem. I believe the problem is worse than my old 260 (which was stolen).

 

One of the reasons I like the Husqvarna 346 XP, is that it is extremely "snappy", both in rev-up and rev-down. Perfect for snedding.

 

- Did any of you guys (and gals) experience this MS 261 behaviour?

 

- Anything that I can do to "fix" the problem (except buying a Husky)?

[WoodED]

erm,,, not without buying a husky no

How tight is your chain?

Chain is as tight as a chain should be ;-)

 

And I can't see how the slow deceleration of the engine could be fixed by over-tightening the chain.

sounds like a badly tuned carb to me. slow return to idle probably meens the low jet is too lean.

Thanks, I'll try making the L mix a little richer. Thought it would only make acceleration quicker, though, but it's worth a shot!

I wonder if the Throttle linkage might be dragging.Or perhaps the trigger pivot is a bit tight?

I think theyt all do it, my new one does.... may be a carb thing.

See how good your local dealer is - the butterfly valve on the carb may not be sealing properly, the carb throttle linkage may be tight, the L setting may be a bit weak, you may have an air leak but shouldnt on a saw that new.

 

On a four month old saw, it should snap straight down to idle - the designer and engineers didn't design the saw to over rev on shutdown so it shouldnt do it!

I forgot to mention that the saw has been acting like that since day one.

Guess I'll take it back to the dealer and see if they can come up with a fix. Not holding my breath, though. I'm afraid it's a common problem with the 261's.

 

I'd be really happy if someone told me: "I've got a 261, and it decelerates really fast"
