Are You Ready for a STIHL?

MS 251 C-BE is rated 4.5 out of 5 by 284.
Rated 4 out of 5 by from Excellent/Good MS251C-Be is an Excellent/Good saw. Starts easily. Worth the extra $$ for the Easy Start feature. The quick adjust is convenient but the plastic chain/bar retainer cover should be metal. If the chain is loose and slips off the bar, it will sever the bottom peg of the plastic chain/bar retainer cover. It's the right hp and size for cutting fire wood and small trees.. I've had it only a few months and I expect it to last quite sometime.

Rated 5 out of 5 by from Fantastic saw, very easy to start, great power, easy to handle. Just bought my 251 C-BE from Walla Walla Saw and Knife today. They walked me through the safety features of the saw and then went through the starting procedure very thoroughly. Got the saw home, fired up on the 2nd pull (first prime the carb, then 1 pull with full choke, then 1 pull on the start position). I have past shoulder injuries and pulling the start on this saw could not be easier. Pull about 1/4 of the way out and the inertia does the rest. This feature is so worth the slight amount of extra money! I let the saw warm up per the owners manual and went to work. This saw has LOTS of power. If you need more power than this, you are probably a pro logger. Very high build quality. Chain has not stretched yet and is still sharp. I really cannot say enough positive about this high-tech and beautiful saw. If you are thinking about an easy to start and handle saw at a very reasonable price, you won't go wrong purchasing this saw. I fully expect that this is the last chain saw I will ever have to buy. Thank you, Stihl, for such a quality product!

Rated 4 out of 5 by from Very easy to start. My wife and I are getting older and needed a saw she could start. Bought a Stihl with compression release but after 3 trips back to the dealer we could not get it to start. Finally got so mad I put the saw on the dealer's counter and told them tp give it to charity. Went to another dealer and they suggested the MS 251 with easy-to-start technology. I bought it and it has been a gem. Starts easily, cuts smoothly. Would like it better with a 20 inch blade.

Rated 5 out of 5 by from Bad Boy Saw, Killing the game! Cut wood like butter and starts 1st time every time and it never a struggle worth the extra money for the easy start. I came from a ms170 and what a difference. AP

Rated 3 out of 5 by from Hard to start,dies,no power We ve had this saw a little over a year and its been in the shop several times ,60 mile round trip ,when it runs it runs and cuts good but im tired of never knowing when its going to start and run ,its had new carburetor put on and still the same thing What i really like is the excuse that its always bad gas as soon as we walk in the door to have it worked on but yet this is the only saw we have trouble with ,another line im tired of hearing is its got saw dust on it so it must run ,yep it runs if it starts,then it misses out ,dies,lacks power Ive got a poulan over 20 years old that ive never had any trouble with and this stihl cant stay running 20 minutes most days The dealer didnt mind taking my money for the saw but acts mad every time i took it back ,but yet i dont see him coming to pick it up and bring it back Stihl needs to come up with a different way of doing the warranty ,if the dealer doesnt want to work on the stuff then we should be able to take it to another dealer that wants to ,which we were told we could do , just need the warranty card that the original dealer wont give up ,but offers me 1/3 of what we paid for it if i trade it in ,like id really deal with that dealer or stihl againAnother thing about the warranty if it cant be fixed after a couple times stihl should replace it so we dont have to keep wasting time and money running around for the same thing ,my opinion on this saw is it was a complete waste of money and still costing me even under warranty
