Carburetor Question

What exactly do you mean about the air and gas? What's it mounted on?

Sir,
No disrespect intended but are you joking about the 2 barrel carb being one side for air and the other for fuel?
Anyway, both sides of the carb provide the engine with an air/fuel mixture. The air flow thru the "barrels" creates a vacuum that draws fuel from the bowl and mixes it as it heads to the manifold.
Take care,

Robert's right- these are the idle mixture screws, one for each barrel. These control the air/fuel mix at idle with the throttle closed. Turn them both in until they gently seat. I usually back them out 1 1/2- 2 1/2 turns and do my final adjusting from there. you can hook up a vacuum gauge and adjust them or just turn them until it runs smooth.
