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.
