electronic ignitiion

I have both a John Player Special and an 850 Commando with 20 year old Boyer ignitions which have been reliable and generally “OK”. The commando has recently started the dreaded “kick back” which is both irritating and painful. I am too old to tolerate this!~ Installed the Tri-Spark and NO MORE kick back which blackened the bottom of my foot and lacerated my shin. Bravo Tri Spark. Next will be the JPS.
