How do you know if your timing is too advanced?
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. Too much advance will cause hard starting and pre-ignition.
How do you adjust timing without a timing light?
to set your base timing without a light, you just turn the motor over in it’s normal direction of rotation until the mark lines up with where you want it.. loosen up the distributor and hook up a spare spark plug to the #1 plug wire.. turn the distributor until it sparks.. tighten down the distributor..

Why do we need to check and adjust ignition timing?
A good indicator that ignition timing may need to be adjusted is when the engine runs too lean (too much air, not enough fuel in the fuel mixture) or too rich (too much fuel and not enough air in the fuel mixture). Having the correct ignition timing will allow the engine to efficiently produce maximum power.
What happens if ignition timing is too advanced?
Ignition Advance Advancing the timing means the plug fires earlier in the compression stroke (farther from TDC). Advance is required because the air/fuel mixture does not burn instantly. It takes time for the flame to ignite the all the mixture. However, if the timing is advanced too far, it will cause an Engine Knock.
How do you check ignition timing?
Connect a timing light to the engine and check the ignition timing. The initial timing should be 12°11°BTDC (Before Top Dead Center). If the ignition timing is not within specifications, loosen the distributor body installation bolt and adjust the ignition timing by turning the distributor.
What rpm do you set timing at?
Rev the engine past the point where your mechanical advance is fully engaged. (Usually, 3,000 – 3,500 rpm will do it.) Watch the timing mark on the harmonic balancer using the timing light. Rotate the distributor until the timing mark lines up at zero with the light.
