No Title

Older 9.9/15 carbs had a 'needle valve bearing' that fit to tip of low speed needle. Your model doesn't use one. Carb kits commonly cover several year classes of outboard's, and may contain extra parts. Included is a pic of that bearing. If that's the part in question, disregard it.

Why is the new style float bigger than the old cork style?

Original cork floats seem to shrink a bit over time sitting in fuel..maybe ethanol fuel?
