Try to get a look behind the small gear at the case seal. Make sure when the metal was flying around in there that it didn't damage it. Also once the motors get run in a little you usually need to re-torque the head. Try a few squirts of wd-40 at the carb and intake tube mounts. If the idle slows you found a leak. Sorry your clutch bearings scattered.
