    My plasma ignition, surface discharge spark plugs, last update, had an unexpected result: simultaneous double sparks:

    Also it’s at about 10.5 to 1 compression ratio on 110 race gas. I’m using the Msd street fire 5520.

    Gary thanks for reminding me about those NGK plugs, I bought a few but never tried them because they run very cold. So what I am using are the Brisk DO10LGS-T which is still a surface gap plug. I guess what I’ll do is run the plug that’s in for now and when it goes bad replace it with the BUE2322 and see what happens. Honestly I don’t think with this much energy any plug will last very long.

    Might be worth a try, but it may also blow the diode. Only one way to find out.

    Did the NGK shunt gap plugs not hold up for you either? I've had pretty good success with them in my Bradley. I have an older MSD unit with fewer joules, so that may be part of the reason why they work for me. I'm also running a 9 to 1 compression ratio on regular gasohol.

    Aaron has moved on to other energy research, it seems, leveraging some of the principles he learned through FE research.

    Hi Heysoundude
    Thanks for comments on my post, I dont know where the black and yellow wire go to, I will have to trace them, I will need a wiring schamatic, will let you know, I still have not heard back from Aaron or Froz, hopefully there still alive.

    hey Realtravel - the second pic of the coil, with the green(ish?) wire just below what looks like the boot of the HV/HT wire that goes to the plug - those blackish with yellow wires at the centred terminal...where do THEY go to/come from?

    That's a surprise to me! All the older Kohler flatheads I worked on used .4375" reach. Is this an over head valve engine?

    Hi Jeremiah,

    Did you ever try the NGK surface gap plugs I recommended back in posts #1093 & #1127? I think the plug I mentioned was the BU8H which has a nickel tip. They also have the BUHW which has a tungsten tip which might hold up better. Here's a link to it at summit racing. https://www.summitracing.com/parts/ngk-2622

    Gary Hammond,

    What plugs have been holding up the best? Every plug I’ve used for a short while has failed by either burning the ground electrode back far enough to cause misfires or just fails internal in some way. Thanks for the help.
