12A Timing

[tom_sprecher]

I know this sounds bad but I do not have a clue about setting the timing on my RX7. It has an oversized crank pulley presumably from MazdaSpeed (maybe has 6-8 1/4"? holes drilled in the face if that tells you anything) that has 4 hash marks milled on it.

Anybody have the same setup? What do the marks represent? What should the timing be? Which plug wire to I use to fire the timing light?

Tom, My car comes out of the trailer tomorrow, and I will answer all if nobody beats me to it.

Here's what the pulley and marks look like.

Tom, google Yaw power for everything you need to know about marking the pulleys correctly (any pulley) & setting the timing.

It looks like a Racing Beat aluminum pulley. If it is then the marks should be as follows starting from the mark farthest away from the pointer: 10 deg ATDC, TDC (0 deg), 10 deg BTDC, and 20 deg BTDC.
