MS 391
MS 391 is rated 4.5 out of 5 by 253.
Rated 5 out of 5 by from Great saw. I have had my saw about 12 years. I loved its easy to start, well running engine and the absorption dampening. Over the last 5 or so years I started purchasing "parts" 440 saws off of ebay and rebuilding them. None of my rebuilt saws run as superior as this 391. I had a three day yard clearing project and this saw still exceeds my expectations. Even after 12 years this started effortlessly and wound run all day.

Rated 5 out of 5 by from Excellent power After owning a few lower grade less powerful saws this was my first jump to a "big boy" saw. I generally use it for cutting large loads of firewood for heating in the winter. My only disappointment came on the first start. I got it home and after a few pulls it flooded quickly and was done for in further attempts. Took it to the dealer who replaced the plug and explained sometimes the first start is rough due to oils used in manufacturing. Home again started on 3 pulls and ran it without load for 5 minutes (burns off oils from manufacturing) after that in the timber 2-3 pulls cold and one quick one when warm and it starts right up. Saw has plentiful power cutting through anything I find and good reliability. Watch the chain, it warms up quick and gets loose, don't let it slip. Other than that a great saw, very pleased with the bang for my buck.

Rated 3 out of 5 by from This saw has ample power. Instruction manual is not very helpful in regards to starting the saw. My saw does not start if it has not been used for a few days if you follow the directions in the manual. Very hard saw to start, generally always floods.Would prefer the old style caps for fuel and oil.

Rated 5 out of 5 by from Great machine. After purchasing several inferior products, a friend of mine let me borrow his Farm Boss, I was totally impressed. Since I have a lot of hardwood on the property, I purchased this saw and it works phenomenal.

Rated 5 out of 5 by from Great, powerful saw! Takes the "work" out of felling trees!! Upgraded to this saw from a smaller, lesser brand a few years back. I LOVE cutting with this saw. A true powerhouse. I burn wood all winter, so this saw gets used often throughout the year. I'm particular about keeping it sharp, and have provided many first hand lessons to cutting buddies on the difference between a sharp saw and a dull saw. I've made plenty of friends envious of the cutting power of this beast. The chain sometimes(not very often) bogs, but likely cause I get antsy and start pushing too hard. I've never regretted paying what I did for this saw. I have a 16" bar I use when I'm doing quick limbing or cutting up a felled tree. The 20" stays on mostly for felling the big oaks around my property. The MS391 is a fantastic tool for any homeowner that wants a truly enjoyable tool.

Rated 1 out of 5 by from Unreliable Purchased this saw and drove 50 miles to do a job and the saw won't start. Take it back to the store and they finally get it to start. Drive back to the job the next week and after a few cuts, the chain comes off and I am unable to re-install it. Back to the store again and they tell me the chain is damaged. I believe the fault might be a defective bar. Waiting to hear back from the store. I have had much cheaper saws that were better than this.
