Well I have been extremely busy with starting a new job, house projects, side jobs, etc. I tinkered with the Z a few days ago and here is what I found with the time allotted. Hooked up a fuel pressure guage and had the right amount of pressure with good volume. Hooked up a vaccuum guage and found a problem. at idle it was bouncing between 10in down to zero very quickly back and forth, and would hold steady at about 13 or so off idle, which I know is wrong, question is, why? I pulled the valve covers off to check for a hammered cam, but running all the rocker arms seemed to have about the right amount of travel, and I re-adjusted anyways while I had them off. I know this may not be enough info to inquire for help, but I only had about an hour... so.
