RE: My firewall is looking left about 1-2 degrees, is that a problem?
To clarify what dragnbye was saying...
How are you looking at it?
If you were sitting in the cockpit, the engine should point straight, or a few degrees to the RIGHT-HAND SIDE OF THE AIRPLANE.
If this is how it is, leave it alone.
If it's pointing to the LEFT-HAND side of the airplane, change it.
