This larger than normal Stihl chainsaw
has been one of the most reliable gas powered tools I've ever had the
pleasure of operating. It gets a bit heavy sometimes to carry, but the
extra power really comes in handy.
Last week it started to sputter and stall and seemed to be functioning
at barely half power.
My first guess was right, it had some bad gas. I poured out the old
stuff and put a fresh new gas oil mixture in and it zipped back to 100
percent. I made the mistake of buying two 5 gallon containers of gas
back in the summer when it seemed like the price was going through the
roof. Now I know how long is too long for storing fuel for our machines.
