Rochester 2bbl Carb on 350 Hesistation/Stall long warm up ?
Hey Guys I have a problem that I am not sure what is going on. Here is what is happening. It has a Chevrolet 350 stock crate engine with 400 Turbo hyd. trans. It has a Rochester 2bbl carb on it. I am pretty sure it is a reman from Autozone (judging from the part # on the sticker on it plus it says Reman on it). I didn't put it on. It came with the car when I purchased it and was already installed. It appears to be a year or so old. It has had this problem since I have owned this car. Anyway, I have noticed that when cold or even slightly warm my car studders(hesitates and wants to stall) when backing out of my driveway. I can even let the coolant temp get up to 175F and it still does this. It attempts to stall. Now if I push the gas harder it seems to all of a sudden get power and back out of the driveway fine. Also, if I start driving it with the coolant temp around 175-180F there seems to be this studder/hesistation while lightly getting on the gas or going up a small grade. If I push the gas harder it gets up and goes without hesistation. I have had other carbs cars in the past and I could fire them up and leave my driveway in a minute or two. On this car I have to let it warm up for at least 5 minutes before I can get out. Now the outside temp today was 88 deg. F. So it isn't cold by any stretch. This is a custom application so telling you the make or model won't help as it wasn't OEM. Here are the part #s on the carb.

What do you guys think is going on? What should I do to try to fix this problem. Maybe it is jetted for economy? It still looks new and doesn't leak. I just would like to be able to get out of the driveway without waiting 5-10 minutes for it to warm up to 195 deg F coolant temp plus I don't like the hesitation when driving with light throttle when cold as it attempts to stall if I don't give it more gas. Now once the car is up to operating temp the car runs great with no hesistation or bogging of any kind. Idle is steady and strong. I just went through the ignition thoroughly. My plugs are a very nice toasty brown. I have a electric choke that is working. Any info would be appreciated. Thanks for your time.
