I have a "hopped up" 1950 flathead that should be timed at 4 degrees initial advance. I know the dot on the pulley is 2 degrees,and the only way I know to get 4 is to measure the pulley diameter and divide by 360 which would be extremely difficult. Can anybody tell me how far from the "2 degree dot" 4 would be? (IE,1/8 inch, 1/16 inch, etc.)I also know with #1 piston at top dread center, would be 0 degrees, but I'd like to be a little more accurate if possible. Regards, Steve Lee

I did the math on mine, but I don't remember the dimensions. The attached picture shows how mine came out, the white dot is on the 2 degree mark. I used the hard stop method to determine TDC and because of my pointer the dot is closer to 4 degrees advanced. I think that the total timing is more important than the initial because it might have to be moved a little to get the total where you want it. That is why I marked up to 30 degrees edit: I just measured mine, 10 degrees is just a little over 1/2". I think each 2 degrees is .112" This message was edited by 40cpe on 6-28-17 @ 7:10 PM

.112" is what in inches (A little less tan 1/8"? or about 7/64 ths. of an inch?)

You're splitting hairs now. Set it about a 1/8 over 2 degrees and then check your total timing. What kind of distributor are you using?

Just use an adjustable timing light. Den

I'm old school and my timing light is a Snapon from about 1963! Regards, Steve Lee
