Wow, your persistent in trying to fix your quad. I noticed that you have a 5k resistor cap, so you are running a NON Resistor plug like the B8ES then right? Not a Resistor plug like the BR8ES plug?
I'm sure you've read/heard that you want one resistor on the ignition circuit... Resistor Plug OR Resistor Cap, not both. Still seems strange that 1-3 have the issue while 4-5 run fine.
Good luck.
