Ok, quick (I hope) question: In the air horn (part that connects to the air box), there are three "ports". One has the air jet (correct term?), one is nothing and is a smooth aluminum hole and the third one is the one I am asking about. I APPEARS to have a very small diameter copper "jet" in it, but I can see no way to remove it for cleaning or replacing. What is this thing? Is it actually removable? How to you guarantee that it is clean and open to the correct diameter?

The removable jet is the pilot air jet, and the non-removable is (I thought) the main air jet. Nate, isn't the starter jet the one pressed into the bowl passage?
Edit: As for the size, I have a set of 78 carbs on my bench and that jet is the size of a #47 drill bit.Last edited by bikerphil; 03-12-2012, 06:09 PM.2H7 (79) owned since '89

Phil, that is exactly how I understand these carbs. the pressed in jet is the main air jet, the screwed in jet is the pilot air jet. Starter/enrichment jet is in the bowl.
If you can spray carb cleaner into that pressed in jet and see it come out in the emulsion tube tunnel with some "gusto". That passage should be clean.Life is what happens while your planning everything else!
When your work speaks for itself, don't interrupt.

They are correct, it is the main air jet. Either way, it doesn't come out!Nathan
