carburetor tool for tri-power

Does anyone make a tool to adjust the idle screws on a 65 tripower center carb? I have a buddy with a flexible screwdriver from the 1960s that will fit around the front carb and it works well. I've looked everywhere and all the flexible screwdrivers now come with a 1 1/2 inch socket adaptor on the end for different bits and it won't bend enough on the end to reach the screws.

This one sure looks like it would work. Might have to grind down the bit end where it seats into the flex shaft, but I don't see why it would not work? https://www.homedepot.com/p/Stalwart...FUwLDAodyNUABw

I have one. The same one I've had since 1981. It's made by Blue-Point (Snap-on). It comes with various socket ends...slot head, hex, even an allen for dwell adjustment on GM distributors. Have used it a thousand (or more) times on as many cars. Really gets in there with ease on any tight carb set-up.

I bought one from Napa but it didn't work. I have a very skinny flat head with a long shafts that works for me. It's one of those screwdrivers that looks like it belongs in the trash can but it has its purpose, lol.

I've tried 3 of those with the Home Depot type socket and they just won't squeeze in there behind the front carb.I'll try the Blue Point.
Many thanks!

Curious what you find as I have been struggling with the same problem....After I rebuilt the carbs I added the port for brake vacuum and installed the factory brake vacuum line off the front carb, making the adjustment even harder.

I don't know if this will fit in the space but this is what I have, I can adjust the Quadrajet with the air cleaner on with this unit.

Goat Roper, that's exactly the one I've been using for the past 37 years. And back then, I paid about $60 for it, so for $69 in 2018, it's a heck of a good deal. It really does a great job on tight screws, and makes dwell adjustment a snap.

Tri-Power carb adjusting

I had the same issues with my 66 tri-power setup.
This is what worked for me.
I really am happy with it.
