Yes, one spring starts advancing at 900 rpm at 20 degrees at 8000 rpm and the other starts advancing at 1600 rpm at 15 degrees at 6000 rpm. I'm just splitting the difference. At least this chart I got says so.

All I could find this week was a single action point and shoot timing light as my other one is in Ireland.

Tape won't do me good cause I got one of them fully illuminated genuine chromium plated accessory timing plates that cover the whole dang harmonic balancer surface right to the very end an all you see is a teeny speck of the timing mark.

Now, I know i'm just making excuses and of course, Mr Severson is elevated and correct and of course would end all the guesswork out of total timing.

But I can't help feeling deflated like a total failure so if you'll excuse me I will now go ask my wife to beat me senseless with my new useless timing light. I will return if I survive.
