The choke should really face the front of the engine. To fix what you have take the carb off the car and pull both fuel bowls. Then remove the screws that hold the main body to the base plate and separate them. Then flip the main body so the choke horn will face forward with the throttle linkage on the drivers side. Bolt the two together and then mount the fuel bowls on each end so the fuel lines are facing the passenger side of the car.
