float valve orifice
Is this the orifice that in the 66 tripower flooding thread folks are saying should be .086 for end carbs and .118-.120 for the center?

If you can not find the original needle & seats you´ll have to measure the orifice with gage pins.
Here are the original part-#´s. Delco part-#´s omittes the 702. |

The information Kenth posted is from the original Pontiac Master Parts book.
The same information is available in the Rochester Carburetor Master Parts book. Rochester also eliminates the 702 AND changes the 38 to a 30. Thus the 1966 Rochester numbers would be 30-03 for the ends and 30-13 for the center. Original reference books such as these SHOULD be on the bookshelf of ALL enthusiasts ! Jon
