Idle Bleed Valve O Rings.
Ok heres a fuzzy picture of my idle bleed valve. I've read some issues with people about the orings in rebuild kits, well I didnt pay enough attention when i yanked the old ones off. Are these orings in the right place? Is it right that the top one is thicker than the bottom?
Wow and I'm dumb substitute the word oring where you see washer in the pic.

It's been 3 years since I rebuilt mine. The old o-rings were pretty chewed up, so I was guessing when it went back together. All I know is before the rebuild, the IAB wouldn't affect MCS dwell, after the rebuild it adjusted right where it should be.
