If you are talking about the big brass plugs in the bowl that provide access to the jets, then a screwdriver (even a big one) is the wrong tool. Those plugs have a curve shape in the bottom of the groove. The proper tool has the curve shape on the bottom of the blade. The Snap-on tool (of course) is the proper tool to use. You can also easily make a tool by cutting a slot in a small socket and placing the correct size grade 8 washer in the slot and weld/braze it in. Use a washer that fits the curvature and width of the plug slot. Then you ca use a socket handle on your new tool and the curved blade will no slip out of the groove like a screwdriver always does.
