Wade, the problem with the manual (at least in my version) is that it says there is some right thrust built into the firewall. Well, mine actually had a slightly negative thrust angle ! I am using a 3 deg Ernst plate to get my right thrust, some went as far as 4 deg. If you are facing the firewall, move the mount slightly to the right to minimise the offset between the cowl opening and spinner. The offset is only cosmetic and doesn't affect flight performance
