Hi guys, my shutter valve on my 12A is wired open. Is it normally closed at idle on the standard intake setup or open? With it being open, will it affect the idle mix? I know this valve nornally closes on decel and opens an air passage to the rear rotor to stop fuel from being drawn. I guess what I'm asking is: does the 12A idle on one rotor or two?

Edit: After a little thought- of course the engine idles on both rotors. Mod's do you want to close this?

Thanks for any help!
