Most found solution for this is to empty the tank and refill with fresh gas.

Ethanol contains in mostly used gas type mowers and over time it can absorb water from the air. If mower has not used for long, the fuel had time to absorb enough water for the fuel not to ignite. Empty the tank and refill with fresh gas. Also, Ethanol-free gas can prevent it from absorbing water. Be aware to use fresh gas after storing. You can even add a fuel stabiliser to keep fuel fresh for longer.
