bro, you can test pulley the Island style way.....turn on the spinner and grab the pulley, lol if pulley twists or burns your hand, then it's not the pulley. If you can stop the pulley from rotating and the motor/shaft is still spinning, then it's the pulley. Just need to tighten the screw/hex....if it's built that way...i never seen the inside of the spinner....
Bring it friday, I can check it out. remind me to bring tools....
