MS 661CM STIHL Review

I figured it was time to try some of this new M-tronic gear out and from what i have read & seen so far well now…. This saw is in my hands all mine i actually love the idea of not screwing with settings. Don’t get me wrong i still have a MS880.

But i love the brain dead days just mix your oil ratio and go….. Will be adding the spark plug sensor meter to this saw just to keep an eye on heat and how this beast runs in the cut. Vids to come…

Now onto the good stuff the STIHL MS 661 C-M ‘91.1 cc’ chain saw is equipped with cutting-edge technologies for outstanding performance. Weighing in at just 7.4 kg and with an impressive output of 5.4 kW, it boasts a low-power-to-weight ratio and is the lightest chain saw in its engine displacement class. Because it’s not just power that counts when you’re harvesting large timber, but also every gram of weight. That makes work easier, even for the most skilled professionals.

Its a Green machine: the efficient STIHL 2-MIX engine with 1-in-4 channel technology delivers high torque over a wide rpm range. At the same time, the STIHL MS 661 C-M consumes up to 20%* less fuel and produces as much as 50%* lower emissions.

*Compared to STIHL 2-stroke engines of the same performance class without 2-MIX technology

The M-Tronic fully automatic engine control makes work easier, even for the pros. A microchip controls the engine’s ignition timing and fuel supply, taking into account variables such as temperature, fuel quality and elevation. So you no longer need to manually adjust the carb, the chain saw consumes less fuel and you can count on the best possible engine performance at all times.

Combi-lever with stop button function

M-Tronic automatically distinguishes between a cold or warm start, so there is only one start position on the combi-lever. The exact amount of fuel needed for each kind of start-up is provided automatically. So you can power up to full speed straight away, even after a cold start. After the saw is turned off, the control lever immediately moves back into the operating position.

Arctic handle package for heated hands oh yes this saw doesn’t screw around when its cold out i keep my little nubs warm.

STIHL Ematic with new oil pump system

The new oil pump system enables the oil flow to be increased, which is particularly advantageous when working in dusty conditions or when using longer guide bars.

I am not looking for a pimped out hotrod saw that i have to dick with all day with a screwdriver. So far i have the ms880 with 42″ and 60″ bars for that… I am looking to work all day long and get as much work done in those hours possible. Efficiency counts here in this conclusion.

Saving me fuel… Ok love it.

Saving me time setting the saw when the day changes or its dead cold out… Ok even better.

Weight Management well to some the guys at a certain chainsaw store they push pens and phones. The first thing out of their mouth is Blah blah Blagh bla blaaaghagaga (they wouldn’t want a saw as big as a 880 or 660 or 3120xp to lug around in the forest let alone mill with). First things first last time i went out to work they weren’t working with me my girlfriend was? Yes my girlfriend…. These guys are pussies that push pens In my opinion some of the guys i have met that have a really cool demeanor to them obviously come with a background of experience (the way it should be). The others that bark with no bite are just chumps that would probably have a stroke in the first hour hiking in. Wow Savoy has really rubbed me wrong last 2 times i went in… Your loss…. Well i found yesterday Woodsman Equipment in Salmon Arm,BC to be loaded with great gear and very good service in which i just dropped fat cash on them… Oh yea we were talking about the weight of this saw. Sweet Jesus sorry for the rant but this saw its a feather.

Looking forwards to sinking this baby into some wood this week and filming lots.  Will be back with some more info on the saw after its been used hard. Thinking this is the way of the new age of chainsaws gives me wood.

Soon to be lost in 160 acres….

This saw is my favorite currently. if i could find a buyer for the ms880 and parts i would buy another 661 and use one strictly for milling logs and the other for cutting people up like the gif represents.
