I modify the pull offs that I sell if/as needed so they apply and release like they are supposed to....

Understood Cliff.
In that case, I have already got both working through modifications of my own. I modify the timing of the pulloff with a short length of nylon screw with the head cut off, a small passage drilled lengthwise and inserted into the rubber vacuum line. Open the drilled hole a little at a time to get the 1.5~2 second release.
As for the short throw one, I bent the mounting bracket rearward enough to clear...so I guess I'm good. The link is buggered up but it does work. That one is a spare carb anyway.

If it works it works. Sounds like a lot of cobbling in lieu of buying the correct parts, but for sure there aren't any rules in this hobby.

Anyhow, below are a couple of pics. First one is an early Olds hot-air converted to E-choke with the more common link that is still available back to the secondaries.

The second is a Pontiac 455 Super Duty carburetor with the correct parts used. This set-up is not nearly as common as the first one and that link is NLA far as I know........

I misunderstood the intent of your previous post Cliff. To back up, I have two 7044266 carbs. One has the original link and pulloff. It looks like the one in pic #2 that you posted. The spare carb has the same link, slightly buggered up but complete, with a different pulloff with two nipples and a too-short throw.. I 'modified' that one by bending the mount back just enough to clear the lever to compensate the shorter throw.
Personally, I'd prefer to have the proper pulloffs in both of them. Just pm me or email what I need..Looks like either of the ones pictured have the longer throw and looks like either link would work? I'm not hung up on correct appearing. After all, I have a '74 carb on my '68 intake and engine.

I stock the correct pull-offs and the links as shown in the first pick. The links as used on the Super Duty carb are not available far as I know. I've made a few out of the style that is when I've had to. PITA to bend them into shape but doable with enough effort.......
