PS22: Permanent Spark Retard

PS22 may be used to permanently restart ignition base timing of 10° BTDC by up to 4° BTDC. When PS22 is selected, the current permanent spark override will be displayed by either "00" for no record or the number of degrees timing was retarded ("94" for 4° retard). Depressing COOLER button retards base timing a maximum of 4°. Depressing WARMER button will display "00" and resets timing to 10° BTDC. Ensure ignition is turned off for at least 30 seconds to save new permanent spark retard value.
