I have read several responses and I have a different read on this. I think that the fuel in the carb goes varnishy and it affects the fuel /air mix. That saw ran too lean and that's what scored the piston and the pot. With the clogging of the jets in the carb the fuel was not getting into the mix and air was constant causing the saw to run too lean. I have seen this happen with a year old snowmobile that didn't have the carbs drained at the end of the previous season.I know gasoline can break down in a few months but the oil in the mix is far more stable than that. I always give my fuel can a good shake before I pour to ensure its all remixed. I have never lost a small engine no matter how long it sits, I use fuel stabilizer and Sthil oil contains a stabilizer anyway...I did lose that snowmobile engine and it cost over $400 for two pistons because it ran too lean..my version and the Skidoo dealers version !
