What is incorrect ignition timing?
Symptoms of incorrect ignition timing are poor fuel economy, sluggish acceleration, hard starting, backfiring, or “pinging” or “spark knock”. Too little spark advance will cause low power, bad gas mileage, backfiring, and poor performance. Pre-ignition can be caused by too much spark advance or too low octane gas.
Why is setting of ignition timing needed?
Setting the correct ignition timing is crucial in the performance of an engine. Sparks occurring too soon or too late in the engine cycle are often responsible for excessive vibrations and even engine damage. The ignition timing affects many variables including engine longevity, fuel economy, and engine power.
Can the ignition timing be adjusted?
The car’s timing refers to the ignition and the process by which the spark plugs fire, creating a spark in the car’s combustion chamber. You can adjust your car’s timing with a timing light and a set of wrenches, tools available at any auto parts store.

Locate the number one spark plug wire on distributor cap and make a tic-mark of this position with a marker pen on the distributor housing.
How do you change the ignition timing on a V-block?
Remove all the spark plugs using the spark plug wrench. The engine will be easier to turn by hand with the spark plugs removed and it’s a good time to replace them if required. Remove the valve cover from over the number one cylinder. On a V-block engine this is normally the valve cover on the driver’s side.

Rotate the engine clockwise and observe the valves on the number one cylinder. When both valves are in the up position, insert a screwdriver into the number one cylinder through the spark plug hole.
What’s the best way to set ignition timing?
This requires using the #5 or #8 plug wire to trigger the time light. Check the timing mark first before setting timing, using both plugs to check the timing before proceeding. The # 1 plug wire is used to set timing when using the top marker reference.
