    IntelliCarb™ Compensating Carburetor
    The IntelliCarb™ Compensating Carburetor is designed to automatically adjust the air/fuel ratio when the air filter becomes restricted or partially clogged and maintains the engine’s correct RPM. IntelliCarb™ uses air from the clean side of the air filter to control the diaphragm and flow of fuel. As the air filter becomes dirty and less air is available for the carburetor, the IntelliCarb™ system adjusts the fuel flow to compensate for the decrease in air flow. This is in contrast to typical carburetors that utilize this air from the “dirty” side of the air box.

    Ematic™ Lubrication System
    The Ematic™ guide bar, when used with STIHL OILOMATIC® saw chain, will provide proper lubrication and less oil consumption than conventional methods. The system works because two ramps, strategically placed in the guide bar rail, help contain the flow of oil and direct all lubrication to the sliding faces of the bar and chain links as well as the rivets and driver holes, which in turn can reduce bar oil consumption up to 50%.

Rated 2 out of 5 by from not pleased withthis ms170, stihl has great products. I got a lemon apparently used one time to cut stump and after 10 minutes of use stoped cutting very well, shut it off and had hard time starting after i had stoped cutting and when It did start acted like it flooded as wouldn't run very well. also chain became dull with the 10 minutes of cutting . took saw back to dealer to exchange for maybe a larger saw , thinking maybe the 170 wasn't big enough for removing the job i was doing but dealer would not take it back for the exchange of a larger model.

Rated 1 out of 5 by from Works great the first time. Then fails. I bought this chainsaw due to the recommendation from a friend. The first time I used it, it worked very well and cut smoothly. After that, it has been nothing but problems. For one thing, when trying to find parts associated with it such as a replacement chain or a file, there are numerous complications. The parts manual does tell you which parts you should get depending on your model, but regardless of which Stihl dealer you go to, the file cannot be found; it isn't carried. And the chains are described in a confusing way that can easily lead one to buy one that seems like the right size but isn't.As for the product itself, the chain becomes severely dull far too easily. I would understand a dull chain after a few uses, but a new chain, or one professionally sharpened by a dealer, becomes dull before the tank runs out of fuel. The owner's manual does not give clear advice as to how the chain should be sharpened. The engine isn't entirely reliable either. I have operated numerous gas powered items and not had a problem, but this one floods easily and needs to be babied and tugged many times in order to start.For those wondering, I have ensured that the fuel was mixed properly with oil, that the lube compartment has never run dry, and that the chain has been properly tensioned. And it was bought brand new from a dealer, not used.

Rated 5 out of 5 by from This saw is great for the money For the money you cant beat it. Its a great reliable saw. I love the ms170. Its great for limbing and small trees. Has more power then i thought. Bought it for small jobs. Looking to buy a new pro saw soon. Its a huge bargain. Your hard to find a name brand chain saw for the price. And with a great dealer like mine. I would buy again if i needed too. A great little saw. Thank you Stihl!!!!

Rated 4 out of 5 by from Bar bolt fell off Overall, the saw has plenty of power, and starts easily. The only complaint so far is that one of the bolts at the rear of the bar fell off during the first use. I was unable to find it, so I had to find a Stihl dealer to purchase another one.

Rated 4 out of 5 by from Rough and small but tough and capable I bought my MS170 on Stihl Days sale and immediately put it to work. I bought it to cut up the smaller branches and yard waste that really didn’t need the MS661’s heft. For that mission the Saw is okay. I plan on upgrading the bar and chain to a 16” Rollomatic ES or E Light that will accept a PS or PM chain. This will give the Saw a bit more kerf and hopefully cure the issue I’m having with the chain itself. The PMM chain is great for my pruner but in the saw I’m getting hammered drive links so badly that it throws the chain off and binds in the bar. I’ve had to file them down 4 times now and the saw does not even have a tank of gas through it yet.. I’m only cutting 3” max diameter brush and having huge issues with the chain. I’m assuming the heavier chain will sort this problem out.The saw runs well though and seems to have plenty of grunt to handle the small stuff with the benefit of being a light weight package at 8.6lb. That being said, it’s not one of the German Made saws either and it does lack the attention to detail afforded to the pro saws. This is apparent in the fit and finish of the saw, however it also does not have the Pro Saw price tag either. Once I get the chain upgraded I’m sure I’ll love it, but it would be nice if it came with it from the factory :-)
