The SE is a newer kit. As such, I would guess that the amount of angle needed is built in to the kit where the firewall mounts so any extra probably isn't needed. If I am wrong and you need to add right thrust yourself theres an easy solution. You will need 4 flat washers sized so that the engine mounting bolts can go through them. When you are facing the plane, the idea is to thread the 2 left side motor mount bolts in a few turns. Then put the other 2 bolts on the right side through the engine mount and put 2 flat washers onto each bolt between the firewall and the engine mount. Start threading the bolts in and go between the 4 bolts turning them in until they are all tight. That will probably give you all angle you will need. If not, of course its easy to add another washer. Hope this makes sense.
