asquaddie Posted April 10, 2008 Share Posted April 10, 2008 I have just recently replaced the spark plug (NGK BR8ES) on my Parajet Volution. Can anyone confirm the gap size - the manual says 0.8mm -/+ 0.1 Just checking, because it seems pretty wide for me and the old one was not so wide? Many thanks Quote Link to comment Share on other sites More sharing options...
weesplat Posted April 10, 2008 Share Posted April 10, 2008 Hi Tony, Sounds about right to me just a little less than 1mm. Havent really moved over to metric my self much more comfy with feet, inch's and thou's standard plug gap is about 30thou but not super critical. As long as it makes the engine go broom its fine.

Phil_P Posted April 11, 2008 Share Posted April 11, 2008 And a couple of tricks of the trade; 1). If your battery or magneto are poor, make the gap a bit smaller so you get a spark 2). If your mixture is a little out, make the gap a bit bigger. The fatter spark will ignite a less than perfect mixture better. Quote Link to comment Share on other sites More sharing options...
