Cold natured!! Does it have to be?

My last Hotrod was really good in the fact that I could turn the key and it would fire right up and run. One of my biggest pet peeves is a cold natured car. This new hotrod, a 77 Camaro, with a late model 350, brand new edelbroke carb, acts very cold natured - when it warms up (about 2-3 mintues) its fine... Can I change the tuning on it or anything else to make it less cold natured? I mean, I live in Houston, it aint cold here!

Sounds completely normal to me, leave it alone if it's running well. Why is 2-3 minutes of warmup unusual/undesirable to you?

Cold natured..................

I know what you mean....some cars will start and idle perfectly right off the bat. My Pontiac is like that. I can get in it, turn the key and drive away.

My truck, however takes a minute or so before it runs decently. I guess it's all in the choke settings, but I just havn't been able to get it just right.

Maybe, it's a slight vacuum leak that seals up once it warms up a bit.............

By the way, theres no choke on this carb

I just don't know what it is?? the only difference that I can tell you between this camaro and my last one is the license plate. Same exact setup 350/Edelbroke carb.

No choke is your problem, it's there for a reason.

Okay....but

okay, but the last car, same setup did not have a choke either... I'm not trying to argue, I just wish I could reproduce the results from before.

Different heads? Different cam?

Lobe sep is one of the "cold-natured" things you can't tune out with carb settings or timing. You can try and acheive some though.

Your last carb probably ran too rich when warm at an idle? ever so slightly at least.
