Yes it does. Clockwise retards it. Counter clockwise advances it.
By rotating the distributor.
I really depends on what distributor you have on the engine. It could be a mechanical advance distributor or a vacuum advance distributor (stock). Google "the Somba" Volkswagen forum and all will be explained.
To advance the timing on a 1996 Toyota Camry, first ensure the engine is at operating temperature and turned off. Locate the timing mark on the crankshaft pulley and the timing scale on the engine. Disconnect the timing advance connector (usually found near the distributor) to set the timing at idle, then use a timing light to check the current timing. Adjust the distributor by loosening the hold-down bolt and rotating it slightly until the desired timing is achieved, then retighten the bolt and reconnect the timing advance connector.
To advance ignition timing, loosen the distributor clamp and in very small increments turn the distributor body in the OPPOSITE direction of the rotor's normal rotation. If you don't know which way the rotor turns, you can find out easily by removing the distributor cap and having a helper turn the engine over with the ignition key switch. To advance the timing turn the distributor counter clockwise.
Distributor Advance is the wrong term; the Distributor Advance system implies actually moving the timing components of the distributor to control timing of spark in the engine (A Vacuum Advance, is an example of this). Modern controls use computer spark mapping, through learned routines or factory set timing models to control the spark based on these tables, through the computer. In all essence it is the computer that controls all spark functions.
Advance the distributor until the engine pings then back off to the point the engine stops pinging, tighten the distributor. This will require driving a few test runs.
To advance the timing on a 396 Chevy, you should turn the distributor counterclockwise. This adjustment will cause the ignition timing to occur earlier in the engine cycle, which can improve performance. Always ensure that you check timing specifications and use a timing light for accurate adjustments.
To advance the timing on a distributor, you typically turn it counterclockwise. This adjustment moves the ignition timing earlier in relation to the engine's position. Conversely, turning it clockwise will retard the timing. Always refer to your specific vehicle's service manual for precise instructions.
To advance the timing on a 2013 Toyota Tacoma, you'll need to adjust the distributor or the engine control unit (ECU) settings, depending on the specific engine type. For models with a distributor, loosen the distributor hold-down bolt and rotate the distributor slightly clockwise to advance the timing. For models with a computer-controlled ignition system, reprogramming or using a performance tuning tool may be necessary. Always ensure to check engine performance and emissions compliance after making adjustments.
To adjust the ignition timing on a 1996 Kia Sephia 1.8, first, ensure the engine is at operating temperature and then disconnect the timing advance connector, usually located near the distributor. Use a timing light to check the current timing by pointing it at the timing mark on the crankshaft pulley while the engine is running. If adjustment is needed, loosen the distributor hold-down bolt and rotate the distributor slightly to advance or retard the timing, then recheck the timing. Once adjusted, reconnect the timing advance connector and ensure all tools are removed before starting the engine.
A vacuum advance mechanism is a component in a distributor that uses engine vacuum to advance the timing of the ignition system. This helps improve fuel efficiency and engine performance by adjusting ignition timing based on engine load. By advancing or retarding the ignition timing, the vacuum advance mechanism optimizes combustion for varying driving conditions.
its the bottom plate that moves in the distributor to advance the timing
