Looks like your exhaust is almost completely closed. That's gonna reduce the draw, and also cause stale smoke to get backed up in the pit. If that's that case, I'd try to keep it fully open, or close to it.
On the cooker it appears to be an older model with slightly thicker metal than the newer COS models. The exhaust already looks like it's pretty close to grate level too. You should be able to make some great food in that thing with a little babysitting. Isn't that what they call a Char Broil Silver? They were supposed to be pretty decent cookers.
