you might see fuel in the line but if the float is stuck shut you will not have any fuel in the float chamber so it will not run. spary some carb cleaner in the intake and see if it will at least pop or take the plug out and pour about a teaspoon of fuel in the plug hole and try to start it.if you got spark it will at least start and run for a second or two.
