I'm a bit concerned with the above statement that indicates that the impulse mechanism is missing and or inoperative, without that you may find it very hard to get a strong enough spark to fire off the engine. The impulse mechanism winds up and releases at a specific point, when it "snaps" the roster inside the magneto is accelerated to a speed the generates the necessary voltage for ignition. Sadly your friend will need to find the missing parts and or a new magneto.

Good luck!
