Im thinking of trying to advance my timing a few degrees, and i heard to do that you need to adjust the CAS clockwise....my question is, where is the CAS? Im a retard at cars. Im hoping someone could describe where its at or if someone has a pic that'd work better. Also, my a/c doesnt work and i cant fix it myself, so Im thinking of ripping it out, how much of a difference would it make in my weight, and would i be able to notice it?

 

(1) It's near the battery, but be very conservative - detonation kills rotaries.
(2) If the AC compressor is good, you might be able to recharge the system.

The CAS is a round metal piece with a black plastic cap on it. It sticks out of the block to the right of the water pump (looking from the front of the car), and to the left of the front housing spark plugs (looking from drivers side fender). It is near the solenoid rack and has a little white plastic connector running to it.
