Need help tuning a six pack

First step - make darn sure your ignition system is top notch. Many a night I spent trying to figure out what carb issues I had only to find out my ignition wasn't right.

There really is no difference between a four barrel and a sixpack. Make sure the float levels are set right and have no vacuum leaks.

You have to get the idle circuitry right first. You should be able to kill the engine by turning the center air fuel mixture screws in all the way or all the way out. This means your air fuel mixture at idle is in the ball park.

Most people don't know this about six-packs but the outboard carbs do have air/fuel mixture screws. They are located in the front of the base plate behind lead seals. The rear carb needs to be removed to set them. I set mine around a turn to a turn and a half (I think) and that got my idle circuitry in the ball park so that the center carb could be adjusted for the best idle.

After that, I used stock jetting with good results.

You might need to change the secondary springs to get the outboards to open at the right rpms.
