Not Ranked
Hmmm...
When you stab it, does it immediately fall flat, or does it pickup for a slight moment, then go flat? In either scenario, does it then start to accelerate well after the hesitation? I'm wondering if your accelerator pump circuit is a problem.
Again, I'm not discounting the possibility that your secondaries are really not opening, but I'm wondering if maybe they're opening too fast instead.
Any chance your paper clip check is faulty? I'm assuming that you're putting it on the rod that comes out of the bottom of the vacuum pot, but doesn't that rod go DOWN as it opens the seconds? I'm trying to picture the vacuum second Holley without walking across the street to the garage. But I'm trying to think of where you could put a paper clip to confirm that the seconds are not opening.
