Re: Quick Quadraject question - Internal Leak?

Sounds to me like the throttle shaft is worn out. A worn out throttle shaft will cause a vacuum leak, thus accounting for the lack of idle change when adjusting the idle screws. A worn out throttle shaft can also cause the throttle primaries to get hung up, thus causing the sticking throttle.
