Note the "buterflys" made from pieces of wire flattened on one side by dragging a number 11 blade over the whole length of stripped plug wire then cutting out 8 short lengths. After they were gluded in place with Micro Crystal Clear, (that gave we time to line them all up) they dotted with paint to make the throttle plate screws.The result is a simple way to make butterflys. The depth of the intake trumpet helps the illusion.
