This is such a dumb question, and its designed to avoid work so its the worst of all but here it goes anyway...
My rebuilt motor has a DUI distributor and started right up but runs rough for the ~60 seconds altogether I have had it going. Clearly some misfires and not "happy." I suspect the distributor may be 180 degrees out of phase. I say that because 1. I did that with another maker's flat-6 motor once and it ran the same way 2. when I assembled the motor I thought I was sure I checked the phasing right, validating cylinder #1 was at TDC and verified the valve positions and the timing BB, but when I went to build oil pressure without spark I couldnt find the BB again until I re-positioned the distributor 180 degrees from where I first had it.
Now, I know some of you will say "pull the valve cover and check at TDC if #1 really is lined up with cap #1 and btdc of the BB. To you, I say "because I had to seal the cover to fix a leak and I really dont want to have to scrape it all off again and re-install.
So, is there an easy fix here by just moving the #1 plug on the distributor to #6, etc...or some other combination? Or do I really have to pull the distributor, rotate and go looking for the BB again?
Thanks!
