Does anyone know what the setting is for the metering rods on a thermoquad. I've got the small TQ that has the 1 3/8" primary bores. 9371S , 1981 dodge truck 318

You talking about the set screw that raises and lowers the metering rods?
 
Yes. Depress the metering rod primary piston until it lightly bottoms in the bore. Hold it there. With a small screwdriver, turn the screw counter clockwise until the primary piston stops going down. Then, slowly turn the screw clockwise taking note where the primary piston starts to move up. From the point it begins to move up, turn the screw 1 1/2 turns clockwise. This is a starting point. From there you can fine tune it by turning the screw clockwise to richen the mixture and counter clockwise to lean it.
