That's a good tip on not disconnecting the PCV. I knew better, just didn't think it through.
When I installed the distributor to begin with I aimed the rotor at #1 while at TDC, just like everyone is suggesting. Since then I've re-oriented the drive gear a couple teeth to get more advance. I'm not really sure where the rotor is pointing now, but that's the first thing I'm going to check before I try again today.
