So funny to watch my "anal" neighbor run his snowblower until it runs out of gas. He does the same to his lawn mower. All of it stored inside. I shove my crap under the eve of my shed with last years gas and it fires up on the first pull.
I park everything with gas in it and have never had trouble. The 2 cycles I have not because I did that 1 year and it took out the fuel lines in the tank. It makes them soft and gummy.
