    I've gone through my '79 Husky 390 OR - it has good compression, seals, reeds and the coil produces a healthy spark.

    Problem - after I start it (not too friendly), it just doesn't have the "giddy up" that a 390 should have.

    I'm assuming the the Motoplat coil also has electronics that advances the timing (like a CDI) inside the plastic enclosure.




    Maybe the coil is OK but the spark is not advancing? Or is it supposed to advance?

    I can get a new coil that works on all these old Huskies - it appears to have a module mounted on the outside (according to my source). It's made by a manufacturer other than Motoplat.

    Anybody have any insight on the problems that can arise with these old Motoplat ignitions?

    PVL seems to be the go-to place for vintage electrical components. Spendy though.

    Is a coil adaptable from another ignition on husqvarna? if not what makes them unique from other systems?

    I can buy an after market coil for about 150$ (it fits all similar Husky's). But then the bike beats me if I change everything until I hit on a winner.

    Besides, I'm too cheap to keep throwing money at this old vibrator. :laugh:
