I've had a DUI distributor sitting on the shelf for quite some time and finally decided to install it. The install went smooth thanks to all of the info I found here on Mud. I turned the key and she fired right up. Seamed to idle smoother than ever. I was stoked!
Here are my question(s).
I have a cheep adjustable timing light. I wanted to set the timing to zero to verify a starting point. Idle <650, vacume advance plugged, timing light is at zero, I twist the distributor to try to get the timing mark (not the bb) and pointer lined up. I turn the distributor clockwise until it won't turn any more, the mark is not visible. Turn it counterclockwise until it won't turn any more (about 1/4 turn), the mark is not visible. So I start adjusting the timing on the light. With the distributor turned fully clockwise and the timing light set at 18 degrees the timing mark and pointer line up? Am I wrong to expect the timing mark to be visible when the timing light is set to zero? I drove around the block like this and it ran just not smoothly. After rechecking everything I came to the same result, timing mark at 18 degrees. As an experiment I set the timing light to 30 degrees (18 base + the 12 the DUI calls for). She runs, runs pretty good. Pulled 4 gear from 1,300 RPM without stumbling. Pulled up a hill with no fuss.
What am I doing wrong? I have a guess but I'd like to get some feedback before I start changing things.
One other question. I don't know what to do with the vent line that runs from the fire wall just behind the windshield washer fluid resoiver to the top of the original distributor .
Thanks
