I can't figure how the gas lines from the tank go to the primer bulb then to the carberator.
what lines go where

Just remember that the bulb pulls fuel from the metering side of the carb, into the bulb and returns it back to the tank, it does not push fuel into the carb, the fuel line in the tank with the filter on the end goes to the carb elbow nearest to the metering side of the carb
