Well, it turns to the left about a 1/2" and you can hear a spring move. It doesn't turn at all the other way.
One of the things the "mechanic" did is that he moved to hose on the carburetor for the advance to the "full vacuum manifold port" that I had it capped. (I have a Holley Street Avenger). He said I'd get more vacuum from there rather then leaving it at the vacuum advance port. So he then capped the vacuum advance port instead.
Is this correct?
Thanks!
