A Quick TQ I.D.

The newer the TQ, the more ports it can have. Pick up truck and larger were exempt from the tail pipe police for a long time so this carbs could, not always, but could also have a lack of vacuum ports.

The newer the carb, well, for the most part, they will have more added on and into the them. Plugging the ports doesn’t always work because the the internal circuitry. If you get a newer TQ, it would be best used as intended and fully hooked up. They can still provide excellent power, mileage, throttle response and in some cases, there was a fuel trim vacuum set up that would help with driving in constantly changing various altitude conditions with the mounted on the front “compensator” attachment.
