I know how. Just need to know the right gap? 0.35 0.18
Generally it's .0125"
But the exact gap isn't important. It's best to have the coil very tight to the flywheel as this will slightly advance the ignition and you will have better performance at operating speed. I use a folded dollar bill to set the gap. Some people use an index card. I find the dollar is easier to use and sets the gap very tight without rubbing.
