I picked my BK Princess up today and started setting up. I chose a pedestal with ash pan and blower fans. When installing the fan with the speed control, the notch for the air control rod is binding the control rod making it hard to turn. I can grind the notch to free it up. My dad has had a BK king since the mid 80’s. I just learned his control was hard to turn recently. He said he has never really had to adjust it so never thought more about it. We removed his fan and that was what was making his air control hard to turn. He used a grinder to free up. Question is, something I’m doing wrong? Regardless, BK makes a great stove and I’m looking forward to this winter. Dad swears by his King. On a side note, my stove did come with a BK hat.
