I've seen many tachs with amber arcs at lower RPM's. Apparently this was the range where carb heat is recommended. Present day marking convention calls for a green arc anywhere that continuous operation is permitted. On the C85 that is from idle to redline. -- John Skyport East www.skyportservices.net
