carb adjustment

If the primaries aren't open you can't mechanically open the secondaries. Even though the secondaries open based on vacuum the primaries limit the amount they can open until they are open all the way.

Also, the secondaries will not open by giving it gas when the car is not moving. You need the load of the engine moving the car to get the air velocity high enough to cause the secondaries to open. If they are working properly you won't feel them open.
