Brief Description: Drilled Mixture Hole in Firewall for Eyeball Ass'y
I crawled into the fuselage and, using the portable drill and the 1 1/8" hole saw, drilled the hole in the firewall for the mixture control cable and the eyeball firewall assembly. I drilled the six 1/8" holes in the firewall for the eyeball assembly. I screwed in the top and bottom holes attaching the assembly to the firewall. the mixture cable was run thru the instrument panel bracket, the lower instrument cover plate, and the firewall.
