RE: First build - Sig SE started

Top mount is installed first then engine is installed to top mount. Access for screws on top mount are through the space between the head and the side. Install bottom mount and tighten all screws. Top engine mount to firewall screws are accessed before the engine is installed. It can be a pain to get all the screws where they need to be but I think it is worth it. The engine mount is the mount that came with the kit drilled to fit the engine then blind nuts installed in the mount. 4-40 socket head screws and flat washers hold the engine to the mount. With the socket head screws you can put them on a allen wrench and through the space above the head.
There are two places that make fiberglass cowls but could not get a good picture to see what it looked like on the plane. Also the cowls were built to fit with the engine setting upright.
