I have been trying with no luck to find the correct engine instrument markings to use on an O-200. I know the oil temp and pressure and CHT red lines from the service manual, but I don't know where to start and end the yellow and green arcs, actually it has been a while since I have flown a powered plane and I can't remember if I need yellow arcs. I know this is an item that will stop the DAR cold so if anyone knows what to use let me know.
I did find some Cessna 150 instrument panel pictures on the net, but they just have the arcs with no corresponding numbers I can use. Perhaps the numbers are in a 150 manual if someone has one handy. Brian Kraut Engineering Alternatives, Inc. www.engalt.com
