I have a Gravely walk behind with a Kohler Magnum 12 engine. The Walbro carb seems to work fine, but when the engine is not running, gas slowly dribbles out of the carb. I've changed the needle valve, and checked the float level - I even adjusted the level a tad so it is a little above parallel when upside down to push on the needle a little more. Nothing seems to help. I wish I could change the valve seat, but it doesn't look like it's removeable. What else can i try?
