I know on a weber its supposed to go str8 to the carb (doesn't matter imo), idk about stock carb but either way, I capped off the advance port on the carb and used one of the nipples on the intake manifold, theres more vacuum there and it advanced earlier with it that way, so it gets better bottom end. I would say that its probly not where the factory put it but u cant go wrong hooking it up there so u should be fine, might even notice a little more power at the bottom end. all it does is use vacuum to advance timing, the higher rpm or load, the more it advances, and with it hooked up to the intake, it will advance earlier, but wont over advance as it can only advance so much. you might just notice a little bit quicker throttle response at lower rpm or when taking off through 1500 - 3000 rpms.
