Thermoquad tuning

Going off of memory, without being exact, the secondaries start to open when the primary throttle blades are somewhere in the 80% open range. This should be plenty of throttle on the primary side for high speed cruising and the ability for a good “Get up and go” response off the line. Even while on the Hwy., the primaries should be able to give enough power to go around slower traffic reasonably well.

No matter the throttle position, the tune on cruise is your target to have a good AF ratio for mileage. I don’t see a Benefit to delaying then secondaries. If you mess with the linkage to delay there opening, you might off set the balance there built with to get the secondary side open all the way when the pedal is fully pressed down for acceleration.

Very seldom do I meet a TQ with purposely bent linkages. The factory settings are excellent as is.

What specific model TQ do you have?
