Engine control holes in firewall
Building an RV7, TMX-O360, constant speed, and want to use "One hole spherical metal grommets" a la Checkoway for the engine controls and carb heat. Using Van's locations on DWG 19 will result in collisions between the grommets and/or very tight fit with the fuel boost pump. Van's tech moving the holes less than 1" shouldn't matter, but to be extra prudent advises hanging the engine first, installing the exhaust, and then seeing whether moving the holes will be an issue. Interested in builders' experiences with moving the holes on a normally aspirated engine.
Secondly, if I use the DWG 19 prop control hole the cable will have to pass between the two brake lines that go to the parking brake. Has anyone building a normally aspirated moved the prop control hole or simply used the hole designated for "fuel injected mixture" on the drawing?
