I just replaced a broken choke on my carb. Now my car idles as 1200rpm in P and 1k in D. Did I adjust the choke wrong, if so which way should I turn it?

MAS,

There is a high idle cam on the right side of the carburetor. It is connected by linkage to the choke plate. The high idle speed is supposed to be set when the engine is at normal operating temperature, and the high idle cam must be manually moved against the choke spring to the high step. High idle speed can then be set to the specification.

Depending on your year, the high idle speed spec can be surprisingly high. For example, a 1984 305 with E4ME carb has a high idle spec of 1,700 RPM. Of course, when the engine is cold it won't idle quite that high, and as it warms up the cam is supposed to back off in steps, gradually lowering the idle speed. When the engine is fully warmed the high idle cam drops out of the way and the normal idle speed stop (on the left side of the carb) is used to control the throttle position.
