Hello,
A while back I posted on breaking a small tube that comes from the bottom of the exhaust manifold and attaches via a rubber hose to the inlet on the air horn of my 2100 carb.
Prior to it breaking I had made a discovery that has me wondering about it's significance.
I discovered that my car had trouble idling nicely with the hose properly connected. When I took it of the air horn, the car immediately idled great, only at pretty high RPM's.
So, now I'm wondering. Is this normal, or is the thing not working properly due to a clog of some kind in the lower exhaust manifold?
Anyone care to explain and get promoted to a higher status along the way?
