I can't make out the numbers on the timing cover tab for the timing light. I know each point is 2* i believe there is 5 points on it like a zig-zag. is 0* on the 1st -top point or the second? A picture would help. I didn't find the pic of mine in the manual. It showed a straight edged rectangle with grooves/#s on it. Mine, like i said is zig-zag. If i know where TDC is on it i can time it. Thanks
