Briquettes advancement

[BrianW]

Ok, so I'm new to this smoker (or any smoker) what controls the the puck advancement?  It seems like when I push the button it will advance 2 pucks off into the bowl,what can I do to fix this? I'm smoking my first brisket and I'm using mesquite bisquettes and I'm not getting alot of smoke,is that normal for mesquite? Thanks for y'alls input. .
