The magnetoes aren't removed to work on the car between rounds---

Back in the day--we ran a single mag--set the timing with the degreed crank hub and a buzzer---mags fire when the points close, so you put the crank where you want it and turn the mag til the buzzer buzzes----

The MSD deals today have some timing retards /rev limiters in them so as to limit the speeds they run--this actually then will retard timing on wheel spin and help the traction occasionally(alltho they all will deny it)
