That part (the CAS) can be installed in 2 different positions. It is important to get it in the correct phase and not 180* out. The car will still run, but not like it should.
Here is a video on the correct way to install it that I made for a lot of people that aren't familiar with it.

also, you should get a timing light and properly set the base timing, which is done by rotating the CAS within it's slotted mounting holes, and then locking it down with the bolts.

Yes, what @Mech Addict stated is the reason the CAS has slotted holes in it, so you can adjust it and it MUST be used to set the base timing at 5*BTDC with a timing light, then locked in place/tightened down at that point.

If you're not a mechanic, setting the base ignition timing might be a challenge. The process is well described in the Factory Service Manual, but again, if you're not accustomed to this, it could end up more destructive than productive. It won't take a genius mechanic, so perhaps a friend who knows how to "set timing", say on an old, carbureted engine. Improperly set timing can cause many other problems if left that way for long. You might get away with a quick drive to a service station, if that's how you will be fixing this.
