New member, first post....

I installed a rebuilt Rochester carb on my 57 Chevy truck - 235. Starts, runs as long as the manual choke is on, but once you ease it off, it stumbles and quits. It'll start right up again, full choke. What am I missing? Thanks everyone !

Check the carb-to-manifold gasket. Make sure that the small hole in carb flange lines up with the hole in the gasket.

The float level is probably set to low. There has been a world of discussion on model B carbs on this website. You might do a search & study them.
"reman" carbs are seldom right.

They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.

Or the float might even be stuck closed, my Holley did that.
