One or two seconds of choke is all that is needed. holding choke will flood engine.

THE GENERAL RULE on cold starts is if engine starts and dies right away you are too lean...

A factory setup carb will run at about 1/4 turn at sea level some need more...

Increase GAV 1/2 turn and retry. if stalls try another 1/4 or 1/2

If very cold some need 1 1/2 to keep running. Reduce as it warms up.

Carbs are different some need more or less to keep running.

BLACK SMOKE AND sputtering? ... reduce ie clockwise.
