Vintage JS550 spark issues

Finally back on the Js550 still working on the spark issue. Spent about a year replacing the exciter, pulser and charging coil trying to get it to spark, swapped in about 6 eboxes trying also in the pursuit of spark. Eventually I jumped the starter solenoid and it sparked off. Now I'm working on getting the ski to fire and run. Any tips are appreciated.
