Lawn mower running rough. Previously this has been caused by a few drops of water in the carburetter's float chamber.
But now I think my jerrycan may have some water in it because having drained, cleaned, and re-filled the mower's fuel system it is still running rough.
Is there an indicator I can add to a sample of the fuel to show whether there is water present? Ideally something like a food dye which I might already have in the kitchen?
Is there a way to make a small amount of water dissolve in the petrol so the engine will run properly? So I can flush out any water in the system.
TIA
