"By the way when I look at the design of this carb I would like to know, when coming to a stop what stops the float from shutting off the fuel? I have heard of stalling problems when coming to a stop. Makes sense because of the design. Why wouldn't it stall?"


I have heard that story about the mini tidal wave inside the Zenith causing the car to stall when coming to a stop. I don't believe it though because a properly functioning Zenith will not stall when coming to a stop.

However, stalling when coming to a stop is a common problem that I have encountered many times when road testing a Zenith I had just rebuilt.

I don't have an answer to the problem. I am sure it has to do with the secondary circuit. The secondary well fills with fuel when coming to a stop and the idle jet picks up its fuel from there. Usually what I do when I encounter the problem is I take the carburetor apart and go through all the passageways again.

The car will stall coming to a stop if you have an air leak somewhere. However when testing a rebuilt carburetor I run it on my Vic that runs fine with its own carburetor, therefore the rebuilt should run as well.
