    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 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 :-)

Rated 5 out of 5 by from Great features, easy to carry, start I have not been able to use my new Stihl 170 chainsaw yet, due to other issues...stay tuned!

Rated 5 out of 5 by from Best homeowner saw for the money I have a lot of pine trees, and with winter and high winds they like to quit and fall over. I also have the MS290 and it was too unwieldy for small and easy pine work, so I bought this. It more than paid for itself bucking up a couple 60'+ white pines. Recently dropped it while falling a maple, and had to let it drop with the lead I was on. Landed on the chain brake and snapped the handle off. Stalled. Picked it back up, pulled the brake back off, and it went back to work immediately. AMAZING saw. FWIW I bought and replaced the brake already, with all the rain here in MD.

Rated 5 out of 5 by from Great small saw I’ve owned this saw for a year and it has been great. The saw is lightweight and cuts very well for its size. Hard to beat the price especially during the dealer days special.

Rated 4 out of 5 by from OK Runs nice, plenty of power for what it is. Is difficult to start even when following the directions to the letter.
