Re: 35HP RD coils

You set the air gap for the lamination to magnet gap. Essentially, you want them as close to the magnets as you can, without actually rubbing, for best spark. There is a mounting boss for the coil, with a flat side machined in it. Pull the coil out as far as you can, where you will not catch the bottom of the laminations with your finger nail, when running it up the flat side of the mounting boss.

There is also a coil locating ring you can buy from FR, which makes it easy.
