Where to add idle bypass air?

(1/1)

Shark Racer:


17059216 carb - where would I add the idle bypass air on this guy? I don't see the passages that I saw in the back of the book.

Haven't slapped the carb on yet, but I'm pretty sure I'll need to add some.

Shark Racer:
OK... just re-read the book. Basically I should go straight down from the holes in the main body and then grind a path.

How deep should the new passages be? Approximately the same depth as the other passages?

I could probably rig this up in a mill.

77cruiser:
Are the holes not there?

Shark Racer:
Are those the bypass air holes? They're definitely there. Wasn't sure if they were that or for manifold vacuum.

I thought bypass air was further towards the front of the carb. (I was looking at the marked up photos in the back of the book)

Shark Racer:
Looked at one of my spare carbs, same era. YEP! You're right.

Thanks! :)
