I've got a two yr old, cheapy WE mower I bought from Kmart. Won't start. I made sure gas lines etc are clear and open. Mower will start if I spray gas into the carb while cranking. The big clue seems to be that it will leak an entire tank of gas out through the little hole in the primer bulb. The engine may or may not be the Husqvarna OHV. Tried finding parts on line but the WE site doesn't show my engine only the Briggs Statton. Any thoughts?
