I noticed fuel leaking out of carberator intake when engine is stopped on my snow thrower. Prior to this I replaced the needle and seat as a tune up measure. Is it possible to put the seat in backwards? I did notice that the rubber seat is groved on one side and flat on the other. I took it apart again and checked the float. I blew in the fuel line and moved the float up and it seems to seal off well. But when i put it back together it still leaks fuel. Where else can the fuel be coming from?  Thanks
