Starting It up

Hey Youmight recognize me from the other forums about what to do with my 305 blah blah blah....anyways I was just wondering when I turn my car on, the rpm's start up sometimes itll start at 700 rpms and run up but either way it ends up around 1500 for a good 5 minutes. What does that mean? Sorry if that was confusing pretty much it runs really high, then I rev it after 5 minutes and it goes down.

SOUNDS LIKE THE CHOKE IS SET RIGHT.WHEN YOU FIRST START IT THE CHOKE TAKES OVER SO THAT IT WARMS UP,WHEN YOU HIT THE THROTTLE,IT KICKS THE CHOKE OFF.

Is there anything I can do to make it ready to run as soon as I start my car up?

I put a new carb with an elec choke on my 80 K20, shortly before I scraped her to build my 82, and wired the choke to a switch with constant batt power. I'd kick the choke on wiat 5 mins fire it up and go, had to let it fast idle in the winter though. I ran it off the run side of the ignition switch on my 82, the way GM did, then you could just turn the key on. The problem with that is it saturates the coil and the module eventualy the module fails. I went through two modules in 8 mos. before I broke that habit. Of course they failed at the worst time, on the freeway. Although you could skip all that and put a manual choke cable on it.

I think you should let it be, thats how the car is soposed to work, you can just get in and go but the car wont be warm and you can hurt that motor
