Title: Ms 660c
Post by: Adrian lucas on September 09, 2017, 08:01:53 PM
Hi all
I was wondering what the general opinion
Was on 661 c stihl very mixed results here in the land down under
Seems they do not like the heat here or the hard wood
Cheers Summercutter

From the info I gather the MS661CM has a very restrictive muffler. Some say opening it up to breathe better solves heat problems.

If you open up the muffler will the auto tune adjust accordingly?  Or do you need to bypass the factory settings?
