I need it adjusting before it can go to a tuner.... otherwise im only going to get as far as my driveway lol

Is it clockwise or anticlockwise? Seeing as the new unit came off a 1.6, im going to have to richen the mixture to cater for the extra 200cc. What is the amount i should be seeing on a co meter anyways for the ZVH? Go by 1.6 ERST or go by 1.8 Escort GTi?
