Yep, I found Todd's and the other posts about it in this thread. I've been considering using the silicone tape I have for sealing faucets, wrap the whole thing with a layer of that and see what happens. That or try to find a slightly thicker washer for the area at the coil deck.
Take a hard look at your 510 screw. If it looks to be leaning off center, take your deck apart. I also recommend not wasting your time adding another o-ring under that screw at the very bottom as per "Todd's review", it only masks and delays the real problem. If that screw is leaning, it means the air tube/disc assembly that it screws into is also leaning, which means that assembly will or already is shorting out against the underside of your coil deck as the whole thing gets sandwiched together.
