moleman Posted June 19, 2019 Share Posted June 19, 2019 Used to , probably still does , time moves on . i would lose the R ( resistor ) and try a plug with an iridium or whatever is fashionable now centre electrode if it’s going on something with older ignition .

moleman Posted June 19, 2019 Share Posted June 19, 2019 If you do a plug chop , don’t use a cleaver! ( first post ) Does what it’s going in have a very good ignition system ? Quote Link to comment Share on other sites More sharing options...
tony27 Posted June 19, 2019 Share Posted June 19, 2019 E=3/4 reach, H=1/2 reach. S is standard electrode ie. the fat type, different last letter refers to shape of the electrode tip 1 Quote Link to comment Share on other sites More sharing options...
