It's a tube on the side of each carb with nothing attached. What's it for? I looked and the parts breakdown shows it on both Cali and other models....I thought possibly it was a California version. It's on the side opposite the air cut valve, it's not the overflow/air passage....so what the heck does it do? After the cleaning bath and rinsing, I hit everything with an air hose...checking passages along the way. If I hit this with the air, I can hear air blowing slightly inside somewhere, but still have no idea what it does.
