If anyone has one that they are positive that it works, please PM or email me at cbmontgo@yahoo.com.

Mine is not working and is giving me fuel mixture issues up here...

I am hoping that someone who desmogged their 2F might have one; below is what it looks like.

Thanks guys.

Until you can find a proper valve, you can simulate what the valve is doing. At this altitude (4000 and up) the valve doesn't change state - the bleeds to the carb are open all the time. The line to the dizzy... I don't rememebr but I think its closed (has Vacuum) to advance the ignition all the time.

Thanks. So I can close off the line from the HAC to the dizzy and that should keep the timing advanced until I can get a new HAC?

Found one on 'Mud from Jim C, so hopefully this will fix my rich mixture issue.
