Nice pics. Now show us a nice pic of the Carburetor. You also said that you had the solenoid?

Have you double checked that the choke rod pushes up when cold? The fast idle step is very visible on the cam on the prim throttle shaft. When the engine (Choke) is cold, just touching the throttle should immediately raise the bolt that moves against the prim throttle shaft cam and put it on...

Adding some TQ eye candy too. A bunch of 6324, one bought from a member on this forum. :thumbsup:

Great info, thanks! Adding wd40 to the gaskets is new for me, would be fun to try.

Agreed, good book. The tricky part I think is to find the correct adjustment measurements for a specific TQ #. For ex, I have the measurements for a Super quad and a 6545...but now I need them for an older type, the 6324.

When I started TQ I got all the books, service manuals etc etc and studied like crazy. Though now I would like to have a book named "How to restore a Thermoquad that is 50 years old". A 50 years old Carter Afb/Avs or Holley is easy, but... Digging into a 50 years old TQ means that you will...

As said above about adjustments after the rebuild: Follow the sequence. If something doesnt add upp, back-track and check again. Fixing a TQ really means digging into details. For the rebuild: -Inspect the plastic body for cracks. -Inspect the glue on the wells, put some gas in the plastic...

Thanks for the info. Though blend the holes in the casting, wouldnt that produce lots of metal shavings? It sounds like it should be done on a bench with a good cleaning afterwards.

The box yes.

Jan 2023. Hard to know which one makes the sound, though my FF box had no hissing noise.

I have the hissing noise too, had it from day one. Cooler installed.

I did drive stock for many years, then changed a lot of suspension/steering parts + a modern alignment. Now my charger is more fun to drive than all modern Normal/sport-cars I have tried. (Havent tried the new Challenger though.)

Then it is a no-brainer. Slap on the 650 AVS2 with a Eddy 9266 gasket for heat protection. A very forgiving combo for the old engine. :thumbsup:

To the OP. Dont stare blindly at the cfm. Choose size in where you live in Rpm when you drive. Especially size of the primary venturi. Check my thread, those tests were done on a 413: My Carburetor journey.

The repop of the Thermoquad is the Holley Street Demon 625/750. Awesome carbs. The 650 AVS2 has smaller primaries than the 800 and will give you a snappier response down low. (If you want that with that gearing?)

That Red lever returns your idle to normal when the choke has been heated up, it does so by falling down. There is another small metal lever coming from inside the choke house that keeps that red lever from falling down until choke is heated up. So, check the spring etc inside the choke house...

Nice going. I am also about to do this on my Indy intake...though what would be a smart way to check that the intake gets centered over the holes in the cylinder head? I guess marking the valley pan is one way.

Check out My Carburetor Journey thread. I went on tinkering til I found max top and bottom in the same carb. My Carburetor journey. Here if you want to test something really fun, it is the spreadbore way you should try out. :thumbsup: For ex an 850 Thermoquad with those really small triple...

Where should it be placed?

Any advice here as I also have the hissing sound transmitting up through the steering column? (I am not in the US.)
