Stihl MS391...a step back?
« on: December 21, 2015, 09:00:12 pm »
Second one on my bench with structural failure......the anti vib system is really weak. Yanked the springs to where they stretched and the handle & saw chassis wouldn't line....It wasn't going to full throttle and I thought that might be why. Wrong. The goofy kluge of a throttle arraignment has this actuating rod that rotates and pushes on another plastic piece to work the throttle and push yet another linkage for the "strato" stuff... That actuating rob is supported and held in place buy plastic load bearing surfaces. It ovaled out. Now to the point it can't push that linkage to full throttle. Wow. A year old saw. All the contact and bearing points are worn.

K.. making a short version. Just focusing on that issue. This poor saw is falling apart under the stress of logging. Anti Vib stretched apart, the vibration is cracking the top cover, and the throttle linkage is wearing out already...will try and email send a vid....do not want it posted please. I plan to erase all related after I send it.

I believe the 362 have the same kind of linkage. I have seen them wear to not allow full throttle or if you flip the saw upside-down the rod will fall out of the holder and you will lose throttle all together.  I would say that pro logging on a 391 is pushing what it was designed to do.  I would like to see the video as well.

You can make any video unlisted or private on youtube so only those you send the link to can watch.

Uploading now....takes a couple of hours. Understand this is raw feed back.. before the editing out of raw emotion! Absolutely don't want this video to linger.
