Timing mark question

[HelmHoltz]

If I am correct when standing in front of the engine with a non-adjustable timing light pointed at the flywheel timing marks, the mark above the 15 Deg mark is 16 Deg and the mark below is 14 Deg?

So rotating the dizzy towards the firewall is advancing the timing?

To simplify: what mark is Advanced? the mark above or below the 15 Deg mark?

Thanks. I found it myself!

Thanks Batever!

"keep in mind that the flywheel is rotating counterclockwise so the marks on it are moving "down" while the engine is running.

So, as per my earlier post, when you rotate the dizzy towards the firewall the electricity gets sent sooner, so the timing light lights up sooner and lights up *before* the red 15 deg BTDC has reached the pointer in the bellhousing. This causes the "shift" in the 15 deg BTDC mark's position, causing it to appear as if it is above the pointer. If you advance the dist by exactly 2 degrees, the light will fire 2 deg btdc and light up the lower (+2 degrees BTDC) mark right as it is just even with the pointer. And the 15 deg BTDC mark will be slightly above the pointer of course.

Maybe not so clearly written, but I hope that helps you understand."

Still confusing, but i will take it, Lower mark is Advanced 2 Deg.
