[T3] Flywheel Question

The 12 V flywheel is slightly larger in diameter. It also has a 
completely different number of teeth. It requires a different 
starter. The 12 V starter has a drive pinion with a different number 
of teeth; it also has a slightly different diameter armature shaft.

The way the flywheels mount to the crank also varies. Sometimes they 
can be interchanged, but it's not a good option, since it's not a 
very good match.
