* Engine Modifications: Has the engine been modified in any way (camshaft, carburetor, etc.)? Modifications significantly alter the optimal timing.
* Distributor: The type of distributor (and its condition) affects the timing curve.
* Fuel Type: The octane rating of the fuel used influences the timing setting.
To find the correct timing for *your* 1965 Mustang 200:
1. Consult your owner's manual: This is the best place to start. It should provide the recommended base timing.
2. Check the distributor: Look for markings on the distributor itself or a sticker under the hood that might specify timing.
3. Find a reputable repair manual: A Haynes or Chilton manual for your specific year and model will have detailed timing specifications and procedures. These manuals often provide different settings depending on engine conditions.
4. Use a timing light: You'll need a timing light to accurately set the timing. The procedure involves connecting the light to the spark plug wire and aligning the timing marks on the crankshaft pulley with the marks on the timing tab.
Without knowing the specific condition and modifications of your engine, it's impossible to give you a precise timing value. Improper timing can lead to poor performance, reduced fuel efficiency, and engine damage. If unsure, consult a qualified mechanic.
