ms391

I purchased a new MS 391. I used it once for no more than an hour. The second time I used it I started it with the chain brake on and let it warm up for two minutes as told by the Stihl Dealer I purchased it from. After two minutes of Idle (chain Brake on) I turned it off and went to start it 5...

Hey AS! Love this community and all the helpful individuals here. I'm up against the ropes with this one. I acquired a few used Stihl saws from fellow who was offloading them, and they are WELL used (price was right). the topic of this post is a old-model MS391. It has served me very well for...

Has anybody successfully removed the port covers on the stihl MS391/311 cylinder? I’m not sure how stihl seals these things on but they’re on there. There’s gotta be a way but I haven’t found it. I appreciate any input. Thanks

Seems the 391 gets the cold shoulder a lot since it’s just a home owner saw. But I did a muffler mod, my way and did not like it, so I was looking for a replacement. Found one one ebay for about $45, nah.... So I started to dig through IPL’s on the 311 and 362 but I stopped short and thought I...
