new single barrel carburetor?

[brizzle86]

1952 3100 235 inline 6 from a 58 to 62 truck.

Truck runs good now and starts fine.

Carb leaks fuel at idle around throttle linkages.

No leak when throttling.

I'm considering having it rebuilt or buying new replacement
Rochester according to there site they bench test all there carbs ready to bolt up.
Current carb has no choke. Should the new one be mechanical choke hook up mechanical linkage?

Which carb do you all think will work for my truck?
