Hey everyone, I'm sure this topic is in here somewhere but I cant seem to find it so sorry if it's a repeat. I have a '71 Riviera with the original Quadrajet in it. When I start it in the morning it has the regular idle. I have to hold down the accelerator to warm it up without it stumbling off. Isn't it supposed to start at a higher idle (what's that called) and once warm I should be able to hit the gas pedal real quick to drop it down to regular idle? I had a '72 that worked this way. I cleaned the carb with cleaner and started it, I see the choke almost fully closed and open up as it gets warmer. It drives fine it's just this cold start issue. Any suggestions? Thanks.
