JNJ55024,
                        ONE THING YOU MITE TRY DOING IS TO CHECK AND SEE IF THERE IS A BROKEN WIRE FROM THE SENSOR TO THE MODULE  AND CHECK THE MAGNET  IS IT BROKEN OR CRACKED IF THIS ENGINE WENT IN AT FULL THROTTLE AT ONE POINT ANY THING IS POSIBLE AND YES THE HALL SENSOR COULD HAVE BEEN DAMAGED FROM THE CRASH JUST BY THE WAY IT WAS RUNNING ON SUNDAY IT SOUNDED LIKE THE IGN. WAS BEING CUT IN AND OUT  LIKE  A  TIMING PROBLEM  I WOULD SAY THAT WHEN YOU CLOSED THE HIGH SIDE NEEDLE ALL THE WAY IT WAS STILL RUNNING ON THE LOW SIDE YOU MITE WANT TO TAKE THE CARB APART AND CHECK IT FOR CRACKS  OR DAMAGED GASKETS
