Check the diaphram on your ZenithStromberg Carb. Sounds like
it has a hole in it.
A hole means the vacuum chanmber that holds up the carb piston
doesn't form a vacuum, so the piston doesn't stay up. With the
piston down, there is only a minimal amount of air flowing, but
lots of fuel - rich, sputter.
