Plus the crankshaft assembly in them is so massive and overbuilt I can't imagine breaking one without a ton of abuse - it's much beefier than the crank in your MS250.
Ummm…. Maybe you didn't read where I said the crankshaft broke on the craftsman saw where you are stating it's so massive and over built that it couldn't break..... Well mine broke..... from a 6-7" tree... Also, it's not what they are made out of (nothing wrong with plastic, it doesn't rust like metal) but how they are made. Well made products just last longer and that's a fact jack. I think I've had this stihl for 3-1/2 years now and still not a single problem. Even after doing a muffler mod and adjusting the carb it still starts easily and runs great.
And yes, craftsman is just a glorified poulan saw..... I'm not a fan of poulans…. I have some and I use the one but it is literally for cutting junk or roots where I don't want to dull my good chain. Use the el cheapo poulan to cut roots or stumps or hell I used it to cut a truck bed liner a few weeks ago. But I wouldn't use it as my go to saw for an all day job.... I'd rather use a light weight saw that runs good, cuts good and doesn't make my arms feel like I was at the gym all week.
I have that same craftsman 55cc chainsaw and it sucks.... Doesn't run worth a crap even with new carb and fuel lines. I gave up on that POS. The "incredi-pull" will fawk your arm up if you aren't ready for the weird spring they use....
I've had a lot of different brand chainsaws and from my experience stihl's are the least problematic.... Not saying they can't have problems but through my experience and heating my house the past 6 years with wood i'd rather spend the extra $100 or 150 for a stihl than a poulan or poulan pro for that matter.... Time = money and I can save time using my stihl….
You can build a deck with a black and decker drill and you can build a deck with a Milwaukee drill but one will be done sooner than the other.... It's like with anything a man uses.... you can make tools work right for a job or you can get the right tools for the job...
When doing an engine build or any kind of work on your truck do you grab the cheap sockets or the good sockets?
