I received my new fuel servo today, which was perfect timing, because it's time to get the engine controls fitted once and for all. The new servo looks great, but I did note that the main fuel inlet is on the opposite side from my old one -- so I will either have to switch it to the other side or order a different fuel line. Also, the fuel outlet fitting needs to be re-clocked slightly.
1. Temporarily installed the fuel servo onto the engine.
2. Re-clocked the fuel outlet fitting to point toward the right side of the engine.
3. Loosened and re-clocked the mixture arm, and adjusted the length of the mixture bellcrank rod end so that the control cable will give it full throw, stop-to-stop. After tightening it all down, I found that moving the mixture control from the cockpit results in a really nice, glassy-smooth action. I love it.
4. Loosened and re-clocked the throttle arm, and adjusted the hardware to give full throw of the throttle. This cable is not quite as smooth as the mixture, and I know why. My cable support arm forces the cable end to swing almost to its maximum throw of 10 degrees off-axis. It's acceptable, but I may have to remake this bracket just to make things perfect.
5. Now that all the engine cables have been connected and their geometry established, I was able to measure the required throws of these components. This will help me establish where to drill the holes in the lever arms of the cockpit quadrant. I assembled the throttle quadrant on the tabletop and measured the total available throw of the levers. (In order to make sure the controls hit the stops on the engine end before they hit the quadrant stops, I subtracted about 1/16" from the available throw numbers. This helped me mark where the holes will be drilled.)
