Now's a good time to fine-tune each threaded rod by hand, watching the carb's linkage arms for any signs of movement. Hold the splined lever arm steady and twist just the aluminum shaft very carefully. You want to take up any slack, but not move the arms when turning the aluminum shaft. You'll probably have to do this a bunch of times, switching between carburetors. Each time you’ll get a better feel for taking up all the slack. This step is necessary to make sure one carburetor doesn’t open sooner or later than the other.

Fill the bleeder tank with your recommended brake fluid, connect the line to the adapter, and then use the plunger to bring the tank up to 15 psi of pressure. It’s not uncommon for air to be in the clear plastic tubing, as this is usually residual from the line itself or the reservoir. The brake fluid, however, will find its way around the air bubbles and into the brake system. From our experience, you can pretty much do this just once and be able to walk around the car, bleeding each corner as needed.
