Engine Mount
I'm a bit confused by what you mean, let me try to explain it better. Instead of being at a 90 degree angle perpindicular to the firewall, the engine mounts are at a angle with the firewall great than 90 degrees, so that instead of pointing straight ahead, they point a bit inwards toward the propeller. This was because when I drilled the holes to mount the engine on the mounts, they weren't lined up.
