Shake Shake Shake

Thanks everyone for jumping in and being patient as I mess with this.

I'm running ported vacuum, so I'm not into the advance when at idle.

Today I started over with the timing. Got it on TDC just to double check it. Then 15 base line advance, and with vacuum advance connected I get 40 total at about 2k rpm. I put the light on all the wires, and they are all firing. I have the idle set just a tad high in the video here. It's about 800 rpm.

The shake is a little better after resetting the timing. Take a look. It sounds healthy, although the video it does sound a little weird, but not in real life. I still have that tapping noise on the passenger side bank. I tried to get that on this video. Maybe I just have a flat lifter?
