Hi dave, I did that, I actually made a sticker so it's on my pulley. I then used a dti to find tdc then adjusted my wire pointer to 0 deg.DaveEFI wrote:I generally make up a timing scale or disc and attach to the crank pulley. Only needs to be temporary - printed out at home and glued on. Mark a true mechanical TDC and use a timing light to check your spark is actually happening where you think it is.
Wheel on the left is a stock wheel with the outer pulley machined off, wheel on the right is the custom pulley.
