Initial timing question??

Initial timing is where you set the timing not started, and at or near top dead center right before firing happens in the #1 cylinder. It is usually set by identifying when the piston is approaching TDC on #1, and is usually set at 12 degrees before TDC. When you start the car, the timing light should show -12 on the timing tab, and any acceleration will move the mark even further advanced until it stops moving. When it stops, your advance is “all in”, and with a tach or dwell meter, you can easily find out what RPM that is. And with an advance timing light, you can find out what degree that is by dialing it until the flash goes back to zero, and reading on the light at what degree that happened.
