hi guys

thanks for your help - i dont mean to step on anyone's toes.

i did a bit of reading on the SL site and after careful measurement of plunge, used a bolt in place of the compensator to play with mixture. for the purposes of diagnosis, i set it rich to the point of not idling properly, and yet, the pinging condition remained unchanged. i can always just refit the compensator and shims, no harm done.

if i stand in front of the car, if the notch on the cam washer is to the left of the pedestal dimple (ie, rotating the engine clockwise brings them into alignment), is the valve timing retarded or advanced?
