Can anyone help with showing what route the fuel lines have. All the fuel lines have rotted so I have no idea. Have tried a couple of different ways without luck. Looking from behind the saw there is a pipe connector on each side of the carb. There are 2 holes in the tank and then the 2 connectors to the primer. So 6 in all. I know which is in and out for the primer so I think it pulls fuel from the tank via the primer then into the carb but which side of the carb? Then there is the other carb connector, is this just a return to the tank? Any help or drawings gratefully recieved. Thanks.
