Spark Plug Question


Recommended Posts

Hi Tony,

Sounds about right to me just a little less than 1mm. Havent really moved over to metric my self :roll: 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.

Cheers Col......

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.
