The Lorax, my FIL rip...
SEM flywheels came in two flavors: the earlier G/E module which used a two part flywheel. It appears from the outside similar to the Bosch, except that it has 4 magnets held on by eight brass screws around the perimeter. The Later SEM G/A module used a one piece cast aluminum flywheel with a single magnet.
Generally, both the SEM setups (G/A and G/E) were reliable.

Ok so I got a little lost with all of this. I've got an 045 av. It won't fire at all. We rebuilt the carb since there was spark when we pulled the park plug out and then cranked it a couple times. Tons of compression. The only thing we could figure was that under compression the spark was too weak. I have the SEM flywheel with four magnets. I'm thinking I need to replace the ignition system but am unclear if the one for
Germany will work or if I must convert to points.

the germany one is a replacement for the bosch system, not SEM. you can get the german one, but then you'll need to source a bosch flywheel.
