Thanks to Smokingbullet for the idea, here are how I cut my air slots out.
Another crappy cellphone pic, but you get the idea, it's quite simple. I used a hacksaw, and only tried to cut on the "pull" direction, or the one that is not as aggressive in biting in. I just cut two that were across from each other, less than 1/16" of an inch. It's plastic, it's less pretty, but this is my outdoor mowing/working device, I don't care.
As we were saying on another thread, it could be possible to raise up the center connector a bit and have it leak more air around it. Some atty/cartos only seem to have about two threads that grab anyway, that would be even less.
