    Backfires... timing? Seadoo 3D

    Just got my engine together.. It's an 05 787cc
    It started right up, but it runs a bit hard... When I tryed to start it again, it was hard to crank and backfired a bit. I guess it's a timing issue... Do I need to back it of or what?

    Thanks, Trond

    Your rotary valve timing is off. Ignition timing will not cause a backfire, at least if setup correctly. Was the magneto cup removed from the flywheel? If so, did you align the magnets on the magneto correctly with the crank?
