Hello , Last week I brought home a little John Deere 3HP engine [Type E]. It seems in good shape, has lots of compression but I cant get any spark. It has a mag and igniter system and I dont understand how that works since the mag has no impulse. However I found that the magnet is broken in two and it also has a broken brush holder,so I think its doomed. I have the manuals for the engine and the mag but they are very vauge. The engine manual states that you can install a battery and coil on it but does not say how and this is where you come in. Could you please help me with a picture or a good explanation.If I could cobble a distributer onto it I would not need any help. Thank You --Harold
