I don't think there's anything wrong with your AGI. Mine is the same. There's really no reason to drill all the way
through on the negative. The grommet is supposed to sit there with the lip above the base. Not sure that it really makes any difference, but I don't like those delrin grommets, so I replaced mine with a silicone one like is used on the AGA-T2. BTW, be careful if you decide to use it as a dripper, because the set screws (on mine anyway) don't seal the base 100%, and it may leak. Todd at
Todds Reviews suggests putting a bit of vaseline in the holes to keep it from leaking, and I have tried it, but it still leaked.

I really got it for the genesis mode anyway, so no big deal. I drilled the air hole out to 1/16" tonight, and it hits like a freight train on my Zmax. I might get brave and drill out the wick hole tomorrow. Also, I found it useful to use a silicone plug like is supplied with the AGA-S and RSST to plug the fill hole as the set screw was a pain in the .....
Edit: There is now a version 2 of the AGI that supposedly fixes the leaking issue. Apparently they no longer
thread the holes all the way through so that the set screws stop and provide a better seal. I'll likely never use mine as a dripper though, so no worries, and I fixed the spring issue, bored out the wick hole, and widened the air hole on mine for use a a genny. If I want to drip, I'll
buy an IGO-L.
