With engine at normal operating temperature, place in Neutral (M/T) or Park (A/T). Disconnect and plug vacuum advance hoses (if equipped).
On all except carbureted B2200, connect jumper wire between timing test connector and ground. See Fig 1 . Ensure idle speed is correct. Connect timing light and set timing as required. See PISTON ENGINE IGNITION TIMING SPECIFICATIONS table. See Fig 2 .
