The core on a lightening similar to a P4?? Not really, its bigger/wider with a lot more drag than the P4 magneto. Same trigger box but distributor/energizer locked in BTDC degrees with throttle coming off the bottom carb bottom shaft output. Snapped belts and belt was slack to begin with along with a host of new and used belts tried. For you it, the CD system in the picts must obviously work, I got tired of broken belts and quit using it. It still snaps the odd belt with a P4 magneto because it still slack though now I use Merc 500 flexplate type cores instead of made for racing flywheels like for the Merc 30H and or 55H. I have this belt slackness on 2 others to varying degrees but the tensioner/idler setup I hear about but have not seen yet. Will have to see how automotive jocks deal with belts to get some idea on inventing a version I suppose.
