Now that I have spark and the slant 6 is running , I want to time it. I have adjusted the valves set the dwell but I am unable to get it timed to the exact spec. I can come close but not exact. If I remove the distributor and rotate it clockwise a tooth I still can not get it exact. If I remove the distributor and rotate counter clockwise same problem. I can get it within 10-15 degrees either BTDC or ATDC but not to 2.5 -5 BTDC as required. The timing mark is not wandering.
Thank you,
Otto

I've never found a difference in the timing when plugged or unplugged.

Then your vacuum advance diaphragm is ruptured or stuck! Get a new one so you can get better mileage and engine performance. Your motor must be pretty sluggish and flat, not punchy......When my pod kicks in it feels like a sling shot!

The distributor is hooked to ported vacuum; at idle it *should* see zero vacuum and have no effect on timing. However, it is best practice to remove and plug the distributor vacuum line while setting the initial timing.

Disconnected the Vacuum advance and plugged and also found the bolt beneath the distributor and loosened it up a bit. I was able to set the timing now . Thank you all for your help.
