I put the unorthodox under drive pulley on when they 1st came out ( I think ) around mid-90’s. I remember how much of PITA the squealing was at start up. Constantly had to be re-tightened over a month then it finally went away. I’ve been gone for so long I remember being the unorthodox under drive pulley was the biggest thing and everyone was doing them. Damn I’m old
