[55 chevy rebuild]

I have a 327 with 3 deuces.
I run on the center carb, the front and back kick in when "needed"
On the center carb there are 2 screw needle adjustments...What is the best way to make sure that these are set correctly?
Thanks for the help.

I ran a 283 with 2 Carter 4bbls, and found that by using a vacuum gauge I could get the best tuning results. Just find a vacuum port on the carb, or intake manifold, and slowly adjust to you get the highest reading, take time to let the engine stabilize between adjustments.

Exactly what Everett said. Just make sure to use a full time vacuum source and make sure the engine is at operating temperature.

I have three 94 3 bolt hollies on an offenhauser intake on a 241 dodge hemi using a progressive linkage system, middle carb for cruising then the front & back carb come in when using more throttle, i have been told to take out the power valves on the front & back carb to avoid the bog down when flat out?
