Working on tuning my '69 350/350 QJ carb. It doesn't seem to be kicking in the secondaries like it should (like my C2 L36's Holley anyway). When driving and flooring gas, there is no distinct secondary kick-in - more of a smooth rise in RPM's w/o the familiar secondary howl.
With the car parked and in nuetral I've reved the engine via the throttle cable trying to open the secondaries but the butterfly hardly moves. As it is, the butterfly cracks no more than 1/4" open. Does the engine need to be under load to create more vaccuum to open the secondaries wider? Is the vac actuator shot? Or is that all I get from Quadraflush?
