On older vehicles timing was adjusted through a mechanical means. There are a set of weights that, when spun, (by the rotor shaft) are extended to advance timing of the spark. At low rpm's they are retracted by a set of springs.

What is the RPM to set the timing on a 1979 305 after you get it running?

around 700 to1000 rpms low enough so the centrifugal advance is not going to effect the timing so you are sure your setting base timing


How does the centrifugal advance work?

Centrifugal advance is a mechanism used in ignition systems, particularly in older internal combustion engines, to automatically adjust the ignition timing based on engine speed. As the engine RPM increases, weights attached to a spring-loaded mechanism are thrown outward due to centrifugal force, causing the ignition timing to advance. This adjustment helps optimize engine performance and efficiency, ensuring that the spark plug fires at the right moment for effective combustion. It allows for smoother acceleration and better power delivery across a range of operating conditions.

What is the 1984 timing advancement for a chevette?

On 84 factory base timing is 8 degrees b4 top dead center and should have no more than 32degrees spark advance total by 3500rpm. You can play around with base timing. If you have a manual trans you can put your base timing around 8-12 degrees and 8-18 drees automatic trans. Each dree you advance the base timing you will have to decrease centrifugal advance as well to keep engine from pinging from detonation. Carb tuning is also a must when timing is changed. Ive personally seen gains of 10 hp at the wheels and up to 15ftlbs of torque with proper timing and fuel curves. Hope this helps. Happy Tuning!

What is an ignition timing advancer?

Ignition Timing Advancers are mechanical 'bolt-on' pieces to advance the ignition timing of the engine to a specific degree of timing advance. The majority of its application for these parts are for motorcycles or on racing applications.

How do you determine proper function of vacuum advance on 22r motor?

To determine the proper function of the vacuum advance on a 22R motor, you can use a timing light to check the ignition timing at idle and then rev the engine to observe if the timing advances as expected. Disconnect the vacuum advance line and check for a change in timing; it should revert to a base timing setting. Additionally, you can apply vacuum to the advance unit using a hand-held vacuum pump to see if the diaphragm moves and the timing advances accordingly. If the timing does not change or the diaphragm is unresponsive, the vacuum advance may be faulty.


Do you need to unhook your vacuum advance when using the timing light?

YES! Any time you adjust the timing you should disconnect the vacuum advance.
