OK, GOT it! Definitely two things: 1. Minor problem is the clutch is "dragging" actually turning at idle. We will deal with that later and 2. Virtually no response until 6000 rpm. Front pulley remove, inspect report/repair. Even if the belt were too narrow, like a bunch of wear or too skinny a belt, you should start to see the front pulley start changing at 2500-3000 rpm.
Good video! How'd joo do dat?
