If the fuel tank can be removed, take it off and clean it, replace the fuel line and filter.
If its not removable, its more involved.
you have to flip over the entire mower to flush the fuel tank, (drain the oil).
Still change the fuel line and filter.
Don't clean the tank with a flush that runs the fuel into the carb.
