Ignitors should have a set of contacts at least 3/16' in diameter, ' would be better yet. If you have only, say, ?' diameter, you don't get the large size arc that you need to really fire up an engine. The points should line up flat to flat.

There's an ad in GEM that has ignitor points for sale at a really fair price.

Gas engine companies made ignitors two ways: If the engine was made to run on a battery, the ignitor points would be normally open, and that ignitor would have an extra spring on it to hold the points open. The reason for this is, while the hit and miss engine is not firing, it is not taking any current out of the battery, and the battery lasts longer.

The other type of ignitor is the one used on an engine with a low tension magneto. The points will be normally closed, which does not matter, as the current is coming from the magneto.

If you are using a battery/coil set up to run an engine that was made to run with a magneto, you can usually hook a spring somewhere on the ignitor to hold the points open, and you will find that your battery will last longer.
