Booster clusters from 2150 carb interchange?
I have a 2150 carb with the variable high speed bleed system. The cluster I have has some major casting defects in it. Can I use a cluster off an other 2150 without any calibration changes?
I have a couple used clusters I found they look the same but they have differnt needles in them. One set tapper gently and the other get fat suddenly at the bottom. Which is best?
Thank-you,
Clayton

It's easier to tune the carb with metering rods that have a gradual taper. If you change the metering rods, you also have to change the cam on the throttle shaft, which is curved to work with a specific metering rod taper. (To change the cam, you have to remove the throttle shaft from the main carb body.)
Booster venturi assemblies are not always interchangeable. Measure the inside and outside diameters on the booster venturis to make sure to have the same size as the ones in the original carb. Also, measure the air bleed orifices (both high-speed bleeds on the top and main bleeds on the front side) to make sure they are the same size.
Heres another thread where I described some problems related to modifying booster venturis (the same issues impact booster venturi swaps):
