Thermoquad help questions

With identifying the rods you have and there dimensions.
You came up with a number that can not be cross referenced with the Vannth guide, so you need to measure the tip and the next one or two steps of the rod.
Let us know the sizes.

The rods hang on the “tree” which has a central, in the middle, piston that rises and falls with vacuum. If your not generating enough vacuum, the tree rises early and enrichens the carb to early giving you that dead stupid rich condition. There is a spring under the tree’s piston. It is larger than an AVS or AFB spring. Delete the spring. In the base plate is a cam that will raise a level for a manual enriching of the carb.

The tree’s center where the adjusting screw is raises and lowers the rods in the jet. To lean out the mixture some at idle , spin the screw to drop the tree downwards. This also delays enrichment.

You won’t get a vacuum signal from the port up front because it is a timed port for the distributor. This is normal and how Chrysler set up the system. It doesn’t see vacuum until you open up the throttle a little. Try from the rear port instead.

You never gave any description to the engine. Compression ratio, cam, headers????
