advance - retard basic question
To advance the timing that that mean that you want the spark to fire when the piston is closer to top dead center? Or is that to retard the timing?
Secondly, when you add higher octance fuel than the car was made for, do you want to advance or retard the timing in general?
Appreciate any comments, love this site, thx
