hi . can anyone give me the ign timing for a 280 watercooled engine , in mm btdc. many thanks in advance

hi all can anyone tell me what the ign timing should be on a 280 watercooled engine, in mm btdc please. i've just found that the ign coils on the inside of the rotor cover had come loose. hence it was backfiring and obviously wouldn't run . iv'e set the coils in the middle of the adjustment limits, and got it running, but would like to get it right before using it again.....many thanks
