Where is the v notch in relation to the indentation?
V notch is to the right of the indentation.
The bright links are only for initial setup. Once the engine has been fired, you can no longer rely on the bright links for timing info. If the gear ratio were 1:1 then they would be in the same spot for every rotation.
Sounds to me like a vacuum leak. Cam timing being off isn't likely to make the engine idle higher than normal. Lower, yes, but higher, not likely.
Hanging up throttle linkage or bent throttle shaft also possible. Assuming the distributor is working ok...
Good to know. I won't worry about the bright link then and just set the cam where it's supposed to be.
Pretty sure theres no leaks, unless it's on the carb somewhere, but I sprayrd carb cleaner all around it checking for leaks and it seems tight.
The throttle linkage and shaft are all OK...and the throttle cable is not holding the throttle open.
