Those are not 1978 or K8 carbs. They look like 1976 carbs. Return spring configuration.

Those two outlets are float bowl vent tubes. Do NOT connect them together.
Just run a tube from each one an down ward out of the way so fuel if overflow occurs will stay away from the hot engine. behind the engine out of the wind.
Put the tubes where the wind does not have great effect on them or it can draw fuel out of the float bowl.
Do not connect the vent tube to the air filter box because then fuel can get sucked out of the float bowls by the carb suction.
