My 2012 696 isn't starting. This past Sunday, I poured two gallons of fuel in via gas can. When I started it up on Monday morning, it ran for two seconds and dies. I siphoned out the two gallons and put three gallons into the tank via a new gas can. It's still doing the same thing. I push the starter button and it chugs but no start. I'm thinking something is blocking the fuel line somewhere but I can't see it from the outside. Is there access to the fuel line somewhere so I can empty the tank again? Siphoning only gets gas from the main tank. Thanks.
