Good question Bill, I have no idea, I will have to look at my Rochester Carb
book to determine that. I am not sure what the choke looks like on the
carb.

As you look down the carb, with the air filter off, you'll see two
sets of butterfly valves. They are flat metal dics or plates, that
pivot on a center shaft. With the engine off, have someone open and
close the throttle while you look down. the futterfly thay moves is
the gas one. Ususally (I think) the upper most one is the choke
butterfly. If the choke is on full, you may not see the throttle
butterfly moving. Gently move it open, and confirm it's not the
throttle one. If the top butterlfy is your choke, when the engine has
warmed up, this should be in the wide open position.

If, when the engine is cold, and the choke butterly is fully closed,
this may be too much choke for your needs/climate. This can be
adjusted, refer to your carb manual or the info posted by another
poster to your thread.

Good Luck.
