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.
