Where is the OAI flapper vacuum source. I think it is from an intake manifold source, just not sure where. Photo would be nice. Thanks!

[SmallHurst]

Yes, intake source for the vacuum. Drop the hammer and the flapper goes open. Same as mine, except a more radical cam.

[SmallHurst]

Sorry, source is behind the carb.

[mockingbird812]

Is it centered on the intake just behind the carb?

[SmallHurst]

Yes it is.

Thanks Rusty!
