Hey all,

I’ve got a GMC 270 with the Carter B&B1 Updraft carb in a 1951 Chevy COE. The carb was completely rebuilt but it’s leaking out the bottom of the bowl every time you open the throttle. I’ve got a video of it which I’ve tried attaching here with no luck. Before I pull the carb, I wanted to see if perhaps there may just be an external screw that just needs to be adjusted or something? Thoughts?

Thx in advance,
Derek
