Dizzy dramas

I noticed in another manual a photo of the TDC mark and the steel ball timing mark being only about 1 tooth on the ring gear apart.
If anybody has a flywheel with clear marks could they please just let me know the rough distance between theses two marks.
The marks on my flywheel are not distinct and are spread over about 50mm either side of the steel ball.

Thanks, Gary

Geez,,thought there might be one good flywheel out there.

 Anyway got it sorted, flywheel circumference ( less timing ball distance inside circumference) divided by 360 deg = mm per degree.

G'day Gary,
 I set my timing by driving the car, first, set it then take off through the gears and if it doesn't ping then adjust it some more. I adjust the timing a little bit at a time, then once it is pinging knock it back so it stops pinging and it is set. You need to be turning the dizzy anti clockwise to advance. If you have no distinct timing mark then it is hard to set to nothing.
If anyone thinks that i am doing this wrong please let me know, because i would hate for this to damage my engine, but i don't know of any other way.
 cheers Scotty

Thanks Scotty, I did manage to get it running pretty smooth.
The guy that sorted my dizzy also sent me some 49 main jets and 60 power valves and this also helped once the base timing of 15 deg was achieved.
It finally goes well and is great to drive.
Gary
