make sure your air filter isn't soaked in fuel aswell. the engne needs 3 things glow on the plug, fuel & air. too much or too little of one & it won't start. try pinching the fuel line closed while you pull the starter cord, if it is flooded it will help it get going. also try starting it with the fuel filter off & see if it helps, but don't drive it round without the filter on, you'll suck in some dust & ruin the engine.
