I just replace the carburetor kit to my craftsman 6.25 HP. When I try to start the lawnmower I start to see all the gasoline going out trough the air filter. Even when the lawnmower was off, it still drain the gasoline tank. What I did wrong?
Sounds like the needle and/or float is set incorrectly or leaking such that it does not stop fuel from entering the bowl once it reaches the design operating level.
