I've had similar issues with the FS distributor that were quickly solved by using different spring rates to play with the advance and retard features of the unit. I have these distributors on both A's and I've tweeked the springs on both of them.


I fully understand those that want to keep their A's just as they came off the assembly line. By the same token bad mouthing an aftermarket product based on a single usage is not always right. As I've posted, been running Per-Lux Ignitors, Petronix Ignitions and FS ignitions (all the same thing) for 35 years and the only failure was caused by me not following directions. Latest installation was a year ago on my '76 Jaguar XJ6c and it runs great. Too, if you're not running the proper coil, you're asking for trouble.
