Put an Edelbrock 1406 carb and 2101 intake on the 85 Chev, 305 engine. Now, when I start it up, it immediately goes to around 2200 rpm. After about a minute to a minute and a half, I hit the gas and it idles down to 600-700rpm. I know this is right for it to step down but isn't 2200 high? Can I adjust that anyway? Choke? It's really bothering me the way it sits up there and screams.
