Rochester 1 Barrel Main Discharge Repair
The Rochester B carburetor can have a couple of different types of main discharge check ball assemblies as shown in Illustration 1. The float bowl on the left is our main concern here. You can watch the how to video below, or read on to get the same information.

Both types of discharge need to be cleaned out, or you could have acceleration problems. The problem with the brass plug type is that they are often frozen into the bowl and when you try to remove it with a screw driver it can break and often does. One way to get the plug loose might be to heat up the bowl around it, but be careful as you could warp the float
bowl. I always try to remove the plug so that I can use it again, only because I tend to like things original, but I don’t lose any sleep when they do break. Do whatever you can to get it out. You can try using a wire with a small hook on the end to pull it out, or use a screw driver to turn it back and forth until it is loose enough to fall out.
