I just bought a new choke pulloff for my qjet because upon investigation (thanks to Lars' writeup) mine wasn't holding vacuum. Anywho, I have the new one here in front of me, and it looks fine except for the nipple hole. The new one's hole is WAY smaller than the old one's. I don't have any measuring devices on hand, so I'll just say with the old, I could probably slip a small finishing nail into the nipple hole, and with the new I'd be lucky if I could shove a pushpin into it. Soooo I dunno. Should I just drill out the new one? It seems like with such a small hole, it wouldn't be able to "react" as fast.

The hole likely should be fairly small. That choke pull-off is also a control so that the secondary bore air valve doesn't react too fast. Even with the small hole, the choke pull-off, if properly adjusted, will open the choke quick enough. I would advise against enlarging the hole.
