Manual choke question

With a manual choke you should depress the throttle 1/4 then pull the choke on while the peddle is depressed, then release the peddle. This will engage the fast idle cam allowing the engine to fast idle once started, (do not touch the peddle once the choke is engaged) when it starts you can slowly push the choke in as required to keep the engine running clean.
If the engine will not fast idle once started you may have to adjust the screw for that on the fast idle cam to increase the speed.
Once the engine is warmed up & can idle on its own push the choke all the way in & tap the gas peddle to release the fast idle cam.
You should be good to go.
You will soon learn the small differences required for your car, but this is the general method used.

Thanks, will give that a try.

Also, are you adjusting the choke so it is slightly open? & are your running manual or vacuum secondaries? If vacuum, are they closed completely at idle?the motor needs an enriched mixture when cold, not a complete choking. If you close the choke completely you shut off all air. Likewise, if your secondary butterflies were pulling open, which is doubtfull, you may be letting too much air in. This is where an Electric Choke is nice. You pump the pedal slightly to engage the Cam & start the engine. The electric choke, if adjusted properly, slowly starts to open. By the time Its open all the way your motor should be idling properly, with the fast idle cam disengaged.

Just pull the damn thing off. You don't need it and you're just going to end up fouling your plugs and then wondering why your car isn't running right.

Its not fully closed, just partially. Was still playing around with the right amount. I have vacuum secondaries and assume they are closed, but haven't verified.
