Dusty... That happened, it moved and my coil shorted out? Should I return it? I'll send an inquiry email.
LOL no.. You need a screw driver, a credit card and a paper-clip to fix this.
Insert the credit card between the movable part on the deck and the solid part, and then tighten the bottom screw. Once it is completely tight, you will notice that the notch in the screw is either lined up with the air-hole or will be at 90 degrees to it.
If it's kinda somewhere in between, then it means that the air hole is not lined up with the hole on the inside of the center post. That's where the paper-clip comes in.
Insert the paper clip in through the air intake and measure that it goes past atleast to the depth of the centre post. If it does not, you may have to crank the screw a little bit to make sure that the holes line up. Does not take much..and definitely not a cause for return.
Best of luck. Let me know if you have any questions.
