1. Some q-jets have a little tag on far passenger side of choke that blocks the secondary from opening. When choke is fully open that should push the tang in and allow the secondary to open. Try opening the secondary by pushing open with screwdriver. You should see how that works.

2. Secondarys open when vacuum is low. Basically a vacuum
Plunger holds them
Closed. As you hammer
The has vacuum drops and the plunger no longer has ability to hold them closed. Think opposite of how your cruise
Control
Works.

Having a vacuum gauge to diagnose is helpful. They rarely open in normal driving. You have to be smashing the throttle down. Just putzing normally you may not see them
Open.
