msq is on the way via email. I increased the spark lead ~ 4* in the 800 rpm bin and heard knocking - but the indicator didn't flash. I guess I need to play with the sensitivity a little. I've set it back to 15* at 800 don't want to adjust spark lead until I get the LED to flash.... it's too hard to hear the knock over the tires, blower and wind.
