Ken and Ron Sounds like the carb is flooding over, and liquid fuel is entering the intake, and is just worse cold. In every application that I have ever seen where the carb was sized properly for the engine, running the idle mixture screw all the way in would kill the engine. If it could run with it at full lean, then the carb was too big, with jets too big, or the carb was flooding over allowing fuel to enter not through the idle port, but through the main metering port which should not be functioning until off idle rpms are seen.
