If the switches correspond to the total loss brains on standup jetskis, You are set up for Rev limit at 12,500rpm, Holeshot 4000rpm, Max timing -1 degrees, retard begins at 4000rpm pulling 30 degrees until rev limit at 1250rpm. You'll need to get a dial indicator and check what the static timing is with the brain set to led mode to figure total timing. (since it is pulling 30 degrees, I'm guessing the flywheel is advanced at least 40 degrees)

Buying a few 4S Lipo Batteries from hobbyking and a cheap charger would be a trick setup for replacing the drill bats.
