I have looked everything over carefully and cannot figure out why once my whole motor is reassembled everything in the upper unit is free and normal but the pull start is very hard and when trying to spin the prop manually it is very hard. There is no grinding or knocking noise, nothing seems out of place it is just not free spinning... any help is awesome.



Did you put in new seals?  Somethimes new seals can make things seem tight for a while.  Same with a new impeller.  Give it a few hours to break in and see if things improve.
