Well your getting a good stream and then your not...that's an odd one.
Usually, good stream but still gets hot. We deal with that one all the time.
Tims original q....was there missing pieces to your impeller when you first examined the water pump?
Timing would effected all the cylinders at once so that doesn't make sense.
Have you done a spark JUMP test?
Testers are cheap....look for a 7/16 blue spark.
