Does anyone know how to adjust timing on a Unorthodox racing crank race pulley (B18c5)? There is only one mark on it. Thanks

(I wish I can trade it for an http://www.inlinefour.com/infourn1encr.html pulley)

 

Use dial-back feature on timing light.

 

how does that work? thanks

 

Set the dial on the back of the timing light to 0.

Shoot the gun at the crank pulley.

Fix your visual reference point on the timing belt cover pointer.

Rotate the dial until the white TDC pulley mark is directly under the timing belt cover pointer. Don't move your head after you've started turning the dial or you could possibly skew it even more.

Read the indicated number on the back of the timing gun for the current ignition timing.

This isn't the most precise method of doing it b/c I've found that most timing guns are off by a couple or three degrees and it's pretty subjective to your POV, so you're really only shooting for ballpark numbers.
