Okay,Richard, let me see if I can explain this so that anyone can understand it.If you look at the top view of the fuselage at the firewall on the plan sheetyou will see two lines going forward to the spinner. The one on the left represents the center line of the fuselage and the one on the right represents the 2.25 degrees of right thrust. Now, look to where those lines intersect at the nose ring. Ideally the center of you motor out put shaft should intersect at that same point. Now the only way you can make that happen is to align your crankshaft center line with the 2.25 degree right thrust line.(1) In order to make that happen start by marking the center line of the firewall from top to bottom. (2)Next measure the gap at the top of the firewall between the fuse center line and the thrust line, then mark that line from top to bottom on the firewall and parallel to the center line you marked in the first step. (3) Look at the side view of the fuselage and notice the line that runs through the center of the spinner and measure from the top of the firewall down to that line. (4) Mark that line on your firewall ( if done correctly it should be at a 90 degree angle to the first two lines you marked on the firewall and running horizontally across the firewall. (5) This step you canuse a protractor of some sortto measure and mark the 30 degree counterclock wiserotation. (6) Next rotate another 90 degrees and mark a line that is perpendicular to your 30 degree line and intersects with the right thrust line and the 30 degree line. (7) Now line up the alignment marks on the side of your mount with these last two lines, making sure that the top of the mountis somewhere between the 9 and 12 o'clock position. I sure hope this helps you. It seems so clear in my mind, but then you would have to be a mind reader to see it exactly as I do.
