Carter (Edelbrock) tuning questions.

I have to agree on the choke, and another plus would be the manual high idle for warm ups if you use a manual choke.
Then next spring you might not even have to use it if you don't want to.
That said, I also agree with 318willrun, in that two steps at a time is the common practice if there is a seat of the pants lean feel. (and obviously there is when cold)
Lets say you have 73/47 rods now, then 70/37 rods would be my attempt.
You can also check your metering rod springs first.
If you have yellow springs now, try pink, as this will allow the rod to come up out of the jets sooner and give a little more fuel earlier.

Man, I hate to see you go through all this over a choke.
It's getting winter time and it's just going to be worse.
