Storing saws

What I read was that oil, not gas, protects carbs.

I'd not feel comfortable putting oil in a carb. New carbs come bone dry. Some of the passages are very very small and oil could clog some of those. Old gas can dry and drop resins (if alcohol doesn't corrode something). If manufacturers wanted to 'protect' a new carb, they would come coated with oil like new chains.

I've done it both ways and could never tell a difference.
All my equipment started either way whether I dumped the fuel or filled the tanks.
I have a $70 push mower bought new in 2011 that has never had the fuel drained and starts on 1st pull every spring after sitting outside for 6 months under roof.
Yes, non ethanol.
Maybe we're talking a year or more.
