I found it impossible to install the engine the way the directions suggested. If I remember right, I taped the cowl on so it looked right and then made a mark on the fire wall that lined up with the center of the hole in the cowl. Next I bolted the engine to the mounts as far to the rear as I could and then set the engine/mount assembly on the fire wall and slid it around untill the mark on the firewall from ealier looked like it was lines up with the propshaft. Transfer the holes from the engine mount and then drill the firewall. As I recall, the instructions were vague about which bolts to use for mounting the engine to the firewall. After you have this done, then you can begin carving out the cowl for cylinder head etc. I don't see how you could ever set the engine on the firewall and then "place the cowl over it and move it around till it lines up" as the directions indicate. There may be better ways to do this, but this is the method I used. Came out pretty close. There is a little offset with the cowl, but not very noticeable.

When you get to the pickle fork for the elevator, I cut the slots in the fuse for it, per the plans then layed the assembled for on the bottom of the plane for reference and made the bends in the fork. To get the ends thru the slots, I used the inner nyrod of a set of plastic inner pushrods and threaded them through the slots and onto th pushrod ends. In my case, the fork compressed enough when I pulled it through the fuse to allow the bends to exit the slots at the proper location. Not sure if I was lucky or good, but the threaded ends were the right length.

Keep me posted on your progress.
