I don't know the real answer, but you do need a gap and this gap will affect performance. -- Oren ...through the use of electrical or duct tape, achieve the configuration in the photo.. |

A match book or bussiness card is just about right

Just shine them up a bit. Nothing serious... -- Oren ...through the use of electrical or duct tape, achieve the configuration in the photo.. |

But it's not a spark gap. There's a gap or space, and it's at the magneto, and it is part of causing the spark, but the spark gap is at the spark plug. |

I worked in a small engine shop many years ago and one of the old timers had us use a business card to set the clearance. It was pretty close to the correct gap and a lot easier to use then a feeler gauge. |
