Details:

The carb ran fine, maybe a little rich, but I didn't get into tuning it. The truck passed smog here without issue. I assume the choke worked, but can't say for sure. I had this running on my C10 square body up until a few weeks ago.

This includes the throttle cable bracket and hot air choke parts everything on that carb two as seen in pictures. This is an authentic, Made in the USA, Rochester 2 Barrel factory GM/Chevrolet carburetor off of a 1976 Chevrolet C10 350ci; 2wd. I'd recommend a rebuild given its age, but it was running when I pulled. I'm replacing the engine and transmission as they need some TLC.
