I use all methods but for fine timing if you wish to run 5 degrees retarded then a timing light is the best method to verify. It is easy to check your timing without touching the distributor. Put light on check and then decide if changes are required.


I recently had a bad timing gear and we replaced it. Car did not idle well and poor power. A quick check with the timing light showed the timing had changed to over 20 degrees retard. Yes the engine ran but no power. Just a few min. and I had it back in its sweet spot.


Use whatever works for you... Now I am a 12 conversion so just hook up. If 6 then you must provide a 12 source to run the light.
