I like the color of your cooker. It looks like the great pumpkin,charlie brown.
I think that you need a wiggle stick for the ash. It is a small wire with a L
bent into the end. You insert in thru the ash door and up into the ash grate and wiggle. I need to make myself one for my next cook. It seems that you can make them from a used bbq fork. Remove one side and bend.
