I just discovered this forum....looks great. Here's a question I asked on another forum a couple of days ago. I need all the help I can get.
I just installed a "rebuilt" Autolite 4100 on my '66 Gt. As soon as I fired the engine , gas started pouring from the carb vents and quickly filled the depressions in the intake manifold . To say it was "flooding" would be an understatement.
Based on my limited carb knowledge and some research, it seems the only possibilities are dirt, a stuck float, a bad needle valve or an improperly adjusted float.
After posting yesterday, I removed the floats and needle valves and blew out the fuel passages with carb cleaner. When I restarted the engine....same flooding issue.
All parts seem as new and moving freely.
Today, I removed the air horn, and found only a small amount of fuel in the bowls and the floats at "half mast".
I then added fuel to the bowls manually and the floats rose as in the pic. Does that necessarily rule out the floats as the problem?
