The manual will tell you the correct timing degrees Before Top Dead Center (BTDC) at a specific RPM (usually idle). Attempting to set the timing without this information could seriously damage your engine. The timing is usually adjusted using the distributor.
To find the correct information:
1. Locate your engine's displacement: This is usually stamped on a metal plate on the engine block. Common 4-cylinder displacements for the 1984 Ranger were 1.6L and 2.0L (though there might be others depending on the market).
2. Find a repair manual: Use the engine displacement to search for a repair manual online or at an auto parts store. This manual will have the precise timing specification.
3. Consult your owner's manual: If you still have it, this is the best resource.
Do not attempt to set the timing without the correct information. Incorrect timing can lead to poor performance, engine damage, or even catastrophic failure.
