Really hard to read your fragmented gibberish, so not 100 percent sure I follow what you're asking but just as a single example the magneto timing for a Continental o-300 is 26 degrees BTDC for the right magneto and 28 Degrees BTDC for the left magneto. That is from the Type Certificate Data Sheet.
