I use only non ethanol gas in my saws. The Echos will start first or second pull after sitting for a year or more. Only have one Stihl remaining. Very frustrating to start until I started giving it a shot of starting fluid.
I’ll be happy when this Stihl takes a final dump so I can replace it with an Echo.

My biggest fear is when I die my wife will sell my guns for what I told her they cost.
