HaveYouSeenAWizardSleep Posted August 31, 2020 Report Share Posted August 31, 2020 On my RX-7 there are two timing marks: Leading: 5 degrees ATDC Trailing: 20 degrees ATDC When calibrating base timing / offset, I had a few questions as I’ve heard a few things that seem quite contradicting. 1. Do I have to alter my rotary split table before entering the calibration table? 2. When setting base timing do I just enter in a value “-20.0”, attach my timing light to the L1 (Leading 1) spark plug wire, and then adjust the offset until the light illuminates when the -20 degree mark on the pulley hits the timing mark on the front cover. I’m fairly new to all of this, so still trying to get a solid understanding of all of this. Just got my engine started by locking my my timing to -20 BTDC and setting my offset to 180 degrees which was a rough guess but still gave the engine the ability to run regardless.
