What is the correct ignition timing for a Chevy 350? The timing can vary between 2 and 12 degrees BTDC, the recommended spark plugs are different and even the plug gaps vary. In most cases starting out with 12 degrees of initial advance is about right. The initial timing should be 4 degrees before top dead center (BTDC).

Does advancing timing increase idle?

It will produce less power(torque) off idle and rev slower. Advance timing, and response increases, easier to start, more power(torque) off idle.

This is measured in degrees of rotation. Most engines set ignition timing somewhere between zero and 20 degrees before top dead center.

How do you check top dead center?

How do I verify my TDC?

Look into the hole with a flashlight to find TDC. Once your thumb has been pushed off the spark plug hole, use a flashlight to peer down into the hole at how close the cylinder is to the hole itself. Have your friend rotate the motor very slowly as you watch to get it as close as possible to top dead center.

What are the symptoms of 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. Too much advance will cause hard starting and pre-ignition.
