Thank you for this. I have never had to mow until I found myself in a divorce and taking care of things myself now. I knew ti wash but wasn't aware it had to be turned on....I know, stupud! Lol
I don't believe that a sucked in gas can has anything to do with ethanol fuel. It usually means that the last time the can was open the temperature was warm, and there were more fumes in the can, usually when the temperature cools down the gases and fumes settle down and contract, creating a sucking in. I never use ethanol, and I have noticed this with large temperature swings.
My neighbor moved the other day and left the tb200. It is missing an air filter and cover. The mower has been sitting in the yard for a few months. It doesn't start. 😢
