What does this do?

I've searched, but couldn't really find an answer (everything just say to remove it). But I'd like to know what the anti after burn valve #2 does. From my understanding, the antiafterburn #1 is basically the shutter valve, which blocks airflow to the secondaries of the rear rotor, but I couldn't figure out what does number 2 does?

Thanks,

Alvin

The shutter valve blocks most of the air flow (and therefore fuel) to the rear rotor on decel. I don't know what #2 is, unless it has something to do with the ACV, in which case you need it for emissions, but not if you don't.

Anyone else want to pitch in?

The #2 AAV is the crappy hose that hooks onto the rear of the intake, and draws air from the air cleaner. It opens on decell, to help prevent backfires.
Funny thing, I plugged mine off, and it no longer shoots fireballs on decell. It also doesn't hold the RPM for about .5 seconds after I let off the throttle.......

If you have the rats nest and cats still in place, leave it alone. If they are gone, cap off the #2 AAV.
