61 2x4 WCFB Jets

[David S.]

Rebuilding 2x4 270HP WCFB carbs. I have tanked and cleaned one so far, rebuilding now. Anyway the book has a note saying the primary rod jets has different openings than the secondary main jets. No kidding, but manual does not say which one has the smaller and larger opening. Anyone know which one is the secondary jet so I do not mix them up. I could pull apart the second carb, but have no clue if that one is correct either. Thanks for your assistance.

David,

Check this out......page 76(pdf pg37) has the answer. The large ones are the primary side. I thought they were as the stepped metering rods go through them.
