Product Description
Distributor Electronic - RKC638EL - 123 Ignition
For the replacement of most 4 cyl. CCW 'Lucas'-distributors
The 123\GB-4-R-V replaces most 4 cyl. Lucas-distributors for engines in Great-British (hence 'GB') cars, where the distributor shaft is turning in a CCW direction.
The unit offers 16 different advance-curves, that can be selected via a little switch. This is a great feature for easy fine-tuning your engine!
It also offers:
- vacuum-advance
- automatic dwell
- spark balancing
- automatic power cut after 1 second
- gearshift retard
Note that there are dedicated 123-ignitions for Mini, MGA & MGB.
Triumph-owners should check if they need a connection for a mechanical rev.counter, as a 123\GB does not offer this.
