What could I do with this Thermoquad?

My bad on the one ring booster comp TQ. I only have one comp TQ and that is the one I have. I assume that is the 1000 cfm model?
I thought the same until someone here posted up differently. It was a dual ring race TQ. These carbs are not seen everyday. I would assume you have the 1,000 unit.
Never thought about the trucks not having emission equipment and I believe you are right.
Cali maybe different on this. IDK. Bewy mentions plugging up the vacuum ports. The ones inside the primary barrels (if equipped) should also be handled. I had one such TQ. I could t get it to go very well. It was a long time ago, so, I don’t know what I missed.
Swapped to another TQ and it was good.

That experience had me thinking it may have been the carb. Or more so something about the year of the carb. This MAY not have been the case. Having a number of them at the time, I just decided it was easier to try another carb rather than pull my hair out trying to make it work.
