Review on Proform Carburetor Jet Installation Tool - 67469 Model by Aaron Schultz

Too big for Edelbrock injectors, round tip on end doesn't fit hole and prevents blades from digging into nozzle gap . (The diameter of the round tip is 0.1755 inch). Like the other reviewer, I also ground down a regular screwdriver to install my atomizers. It looks like it would be a good idea to install atomizers with a top opening big enough for the tip to fit. Inside. about 3/16 inch or more. The shaft diameter is .316" (not a problem on my Carter BBD but can be a limiting factor in some applications).
