Charles,
Most adjust the alda "altitude compensator" by checking for smoke out the tail pipe, yours is probably ok if you get a trace of smoke under hard acceleration.
To adjust you need to remove the plastic seal on top, which is very tedious with an exacto knife, dental picks, and tweezers. There is a lock nut and screw in there and you hold the lock nut and turn the screw out to richen.
This does not change much and you have a good chance of ruining the alda. If your seal is intact it's not been adjusted, Ca. emmission not in effect on your car.
