That smell and the noise you reported makes me wonder if the bearing in
your pulley is bad or going bad. I've run a Code 3 for nearly 2 years, off
and on for the 1st year and steadily over the last year with no problems or
smells (well, I sometimes get a little chirp when the pulley engages, but not
all the time).

Instead of the screw driver and wedge block, get a strap wrench to hold
supercharger drive wheel in place while you loosen or tighten the pulley
bolt. They work great for this purpose. I would also recommend that you
check the pulley mount for anything that might cause the pulley to stick
to the mount and buff it out. The pulley can be a real bear to get off
when it's stuck, but a little vibratory wiggling usually gets it clear. Wear
gloves while trying to pull it off. Better grip and better protection for your
hands.

Hope you enjoy the Code 3 as much as I have. Good luck.
