advice needed on HM80 loose magnets on flywheel

I bought an old snowblower with a Tecumseh HM80 engine. (model HM80-1551 27B S/N 5258D) The inside diameter of the flywheel has rusted badly including under the magnets so they are no longer attached to the flywheel. I sanded the rust lightly but cannot find any witness marks showing where the magnets should be.
1. Could someone give me the angular location of the magnets relative to the keyway? Is there a space between the two magnets? Should the magnets be flush to the edge of the flywheel nearest the engine?
2. Any suggestions to bond the magnets to the flywheel? I was going to use J-B WELD for steel hoping it could handle the vibrations.

JB weld is what I use to reattach magnets, but it is usually obvious where they go from the old glue on the flywheel. Get a used flywheel just to use as a reference.
