[Healeys] Spark plugs renewal

[Earl Kagna]

I run .030 on both Healeys – both cars have sports coils installed, the tri-carb has a Pertronix, the BJ8 a 123 ignition (cleverly installed in a Lucas distributor body).  It’s not so much the ‘switch’ – points or one of the electronic ignitions that should determine the plug gap, but the coil output needed to fire across that gap.  With a standard coil, I would stay at .025 as recommended, regardless if the type of ignition used.

Have heard somewhere, possibly Pertronix, that you can increase the nominal gap by 0.005" with a Pertronix Ignitor.  I went conservative; I think 0.030 would work with a good coil and secondary wiring.

  The reason I asked is that I was told .035 which seemed a bit too large a gap for some reason.

  I'm running 0.028" on my BJ8 with Pertronix, and could probably go a bit wider.

    What gap do you set your plugs when you are using the Pertronix?

    OK Steve – I’ll bite:  What caused the change from Champion RN12YC to NGK BP6ES? 



    Your having kept the Champions in for over 46,000 miles would usually lead to conclude you had a good to great experience with them.



    On the other hand, to change brand after all that time and mileage would seem to indicate just the opposite!



    Inquiring minds want to know…
