Ignition Timing ?
Can anyone tell me the correct ignition timing for my "87 N/A. I have timed it "by ear" and have it running OK, but when I put my timing light on it, it reads like 60 to 70 degrees advance. If I move it much off that setting, it barely runs. I am using a Craftsman light with the dial advance on it. Is that my problem with 3 fires per rev instead of 1 every two like a 4 stroke??? I would like to get my timing to spec., because it seems to have a big effect on high RPM power but that is hard to tune by the seat of my pants!!!!
Thanks for the help!

To time this car correctly, set the timing light for 0 degrees advance, connect to a leading plug wire, and set it so the yellow mark aligns with the pin. If you absolutely positively must mess with the advance gizmo on the timing light, set it for the same setting as you would for plug #1 on a GM 4-cylinder with DIS ignition (2 fires/eccentric shaft revolution). Good luck!
