Title: smaller sprark plug gap for Mag.... why? Post by: Peter on December 04, 2014, 13:15:26 pm I ve been thinking about this...
everybody says a mag delivers a hotter spark than whatever... ;D Now if that would be the case, why is there the need to decrease the spark plug gap when using a mag? I thought when the energy is higher, you can increase the plug gap??? Is it to overcome the low energy the mag has when starting ( like low rpm's) Peter Title: Re: smaller sprark plug gap for Mag.... why?
