Pic 3 shows the throttle controls as described in the manual but that configuration is not acceptable because the fixed fore and aft rods are not horizontal to each other and that disrupts the beginning and end travel of the throttles. I eventually reworked the rear cable so that the rods were more in line with each other. This fix improves the full stop positions on both the forward and rear throttle positions. I may have a picture of the improved linkage and will post when I find it.
