Has anyone ever R&R'd the air flapper mechanism on an early 911? The part number is 911 108 015 00 and is called a Regulator Housing. I think it was an emissions device added some time around '71. Anyway I mistakenly took mine apart rather than just removing it and now I am having trouble with a spring inside. I went to PET but could not find an exploded diagram.
This is it installed
BTW - do I need it?
