I watched your video over 20 times....I wanted to do exactly what you said to do - My washer would work ok but not do that 'fast' spin - 
I took out my dripping clothes and decided, I can fix this! - I replaced the coupler and the clutch like you explained and now it doesn't spin at all - 
I don't know what I did - It used to spin - well, I took it apart 3 times and I still can't figure out what's wrong - help!!!!! - please!!!!!!
