Re: Rochester carb help possible bad linkage
That open port is ported vacuum. Put a cap on it. It’s a vac leak once the throttle opens a bit.
That yellow circled pin is normal. It’s the bottom end of the accelerator pump linkage. It doesn’t contact anything.
There should be an arm that contacts the secondary linkage (black circle)when the primary is opened about halfway. It looks like yours has been modded to hook up your tv cable.
