Mine exit just starboard of center and just above the crossbar of the engine mount. I wanted a straight shot at the terminal mounting hardware for the mixture and throttle fittings. This seemed to be the best place. Your engine and carburetor should maybe be in place to approximate where you want them to come out. OR just measure starboard of center somewhere. Make sure you miss the crossbar.... If you can estimate where the mounting hardware is going to be, you might be able to just have the engine mount on without the engine. I can't remember exactly how I lined mine up. It might be in the plans... The space from the firewall to the mounting hardware, as you can see, is quite short in a -4. This is for an O-320 but is probably similar.....Any recommendations on the 4 firewall pass through location for these 2 cables, using a O360 lycoming carbarated with out constant speed gov.
