OK- if you have an electric choke stat, make sure it's getting power ONLY when the ignition switch is in RUN. Also make sure it's grounded. Aftermarkets have a ground wire; OEM grounds thru the choke housing so electric units have no insulator gasket between the housing and the stat. This is also a good time to make sure the small engine-to-frame or firewall ground straps are in place.

See if there's an index mark on the choke stat. If there is, align it with the correct notch on the choke housing. 1965 shop book calls for "index" setting on everything but stick cars, meaning you align the mark on the stat with the middle notch on the housing.

If it has no indexing mark, or if adjusting it by the index mark is obviously too lean or too rich:

Engine warm enough for choke to be fully open and normal idle speed, engine stopped, aircleaner off.

Loosen the 3 choke stat screws, hold the fast idle cam up out of the way, and slowly rotate the choke stat in RICH direction until the choke flap closes and is just lightly touching the air horn. Then move the stat one more notch rich and tighten the choke stat retaining screws. That will give you a baseline adjustment to work with.

You can then tune the choke stat to give the desired fast idle and choke time.
