Pete, I chose the name grumpy, so I can hardly object to anyone calling me by it.

It sounds as if you understand the layout of your magneto, so the next step is to check some basics of its operation. We need to know if it is an electronic type or a breaker point type. If it has points they will be fairly close to the crankshaft, and are just two flat pieces of platinum, one of which is moved up and down by a cam (bump) on the crankshaft, so they are usually inside the flywheel on small engines, especially 2 strokes. You said previously that you looked inside the magneto without removing the flywheel, and found some contacts. This is a bit worrying because if you opened up an electronic magneto and disturbed some contacts, there might be a problem now getting it to work again. On the other hand, your wire that goes under the flywheel might go to a set of breaker points inside the flywheel, and since you haven't had the flywheel off, that probably isn't the problem area. Can you post a picture of the magneto and tell us more about what you did and what you found, when you opened it? This is the most likely location of the problem.
