Point gap

By the way the closer the points are together the higher the engine Revs. That's why we used 16 quite a bit.
Now here's some more info for you. You will notice that the spring for the point has a slotted opening where you hook the wires up that go to the coil and you hook your condenser to. Now if you push the spring in to where it shortens the points spring that gives you more tension on your points which also allows you to rev higher.
The negative side of having more tension on your point is that you will wear them out quicker and have to replace them sooner.
