Timing with Advancing timing light

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   A friend suggested I set the timing on my 1968 LM318 Chrysler(with new prestolite electronic ignition distributer) with a advancing timing light by running the engine up to 3000rpm and setting the timing to 26 degrees. The timing is normally set at 5 BDC at 550 rpm. He suggests that this method eliminates any timing variables introduced by the mechanical advance built into the distributer. Anyone use this technique? Any thoughts on the subject? Thanks ,Jim B.

	Its always good to understand you max advance, but its not licence to roll back the advance at idle. Something is going to compromise. 26 degrees doesn't sound like nearly enough final. I predict if you do as he sez it could pop and fart of accel due to not enough initial. Use the light to map your advance curve, you can learn a lot. Know what initial your boat likes, and the final, then set the advance span for the difference, then if you set inital or final, you get the same result.
