Unfortunately I had a mechanic check the timing, as I do not have a timing light. So no idea if the advance is working, but I was told timing was right at spec. Would issues with the advance cause a rich condition off throttle? The timing advance housing is rusty, no idea how it looks internally. As for fuel system, it is right around 36-37 PSI (brand new regulator, injectors, pump, and rubber lines). I will pick up some feeler gauges this week to check valve lash.
