I have a little MS 250 that I use for corral work.
It recieves zero maintenence and has been a great saw. Tool less chain tension, captured spring start.....which I dont think they make anymore.....and the Stihl quick caps.
When I finish using it for the year is it put in the shed....I use premium with no corn squeezings and Stihl oil and never empty them out.
I treat my 460 Magnum and my Pro Mac 850 more nicely.
