spark plugs fouled up Ground, wires bad ??

Question for the audience

Car: 1979 930 with an 83 Euro engine 65K miles

Problem: 4, 5 & 6 spark plugs very very rich, 1,2 &3 just a bit rich

Info: I just did a complete engine rebuild, injectors spark plugs, distributor , rotor etc and I did not replace spark plug wires. I know spend all that money and not do them...They looked fine. no breaks shiny etc

What could cause the right side to foul up. BTW...I am chasing a Air fuel gremlin which I am about 90% sure it is the WUR

ground ? wires? too much fuel on right side, Would the WUR cause this and if so...why the right side. Longer fuel lines?

Need advice...Thanks all

1979 930 - Black on Black and in the woods
