I'm trying to get the ignition timing specs [i.e. deg. before TDC] for an '89 Omni / Horizon; 2.2 litre; throttle body fuel injection. My Haynes manual says it's on a sticker in the engine compartment.... but the engine isn't in a car; I have it in a homebuilt trike. The dealers around here all say it's so old the info is no longer in their computer systems. Thanks in advance for any help. Owen.

12 degrees BTDC. If you are still using the factory computer somehow you have to unplug the coolant temperature sensor while checking timing to get an accurate reading.
