Hi all: I need to ask if anyone can post a photo of the timing scale for a 1988 Sunbird GT 2.0L Turbo. Mine's missing and I'm trying to figure out how to set initial timing. If someone has a photo, maybe I'll have a better idea of where the timing should be set - I might even be able to fabricate a crude scale that I can attach. I see one notch on the harmonic balancer, but have nothing to time it to. I know once the 4-wire ECM connector is connected, the ECM then controls ignition timing, but I want to be able to set initial timing before turning control over to the ECM. If anyone knows where I can get a replacement scale, that'd be great. Appreciate any hints anyone may have.
