<div dir="ltr"><div class="gmail_default" style="color:rgb(51,51,255)">A guy named Alan Smith had a garage on South Beach full of old Rolls-Royce's dating from Miami Beach's heydays in the 20's and 30's. He described himself as a certified RR mechanic but I believe he was simply a professional chauffeur who had a classy English accent. Nevertheless he knew his stuff and as an aspiring gearhead I used to hang out there. I had a TR3 with a radio and I remember asking Smith what he thought about putting an inline resistor into the distributor to coil wire. He shook his head and simply removed the wire, tied an overhand knot in it and reinstalled it. <i>Voila--</i>the ignition noise was gone.</div><div class="gmail_default" style="color:rgb(51,51,255)"><br></div><div class="gmail_default" style="color:rgb(51,51,255)">Best--Michael Oritt</div></div><div dir="ltr"><div class="gmail_default" style="color:rgb(51,51,255)"><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Mar 19, 2023 at 10:25 AM <a href="mailto:josef-eckert@t-online.de" target="_blank">josef-eckert@t-online.de</a> <<a href="mailto:josef-eckert@t-online.de" target="_blank">josef-eckert@t-online.de</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><p style="margin:0px"><span style="font-family:arial,helvetica,sans-serif;font-size:10pt;color:rgb(0,0,0);text-decoration:none">I do not care what kind of noices are<span style="color:rgb(34,34,34)"> in nearby vehicles.</span><br></span></p>

<p class="MsoNormal">I do exactly what Bob does with my BT7 except I use a non-resistor plug – Champion N12YC and 0.028” gap. I too use a Lucas Sports coil. I always thought the resistor plugs were to introduced to supress interference with car radios, which I don’t have, but I am happy to be corrected on that. I think plugs are unnecessarily changed too frequently. I remove them once in a while (every few years) and clean and check the gaps. I run them until they shows signs of deterioration. I have never had a plug fail me in the Healey.<u></u><u></u></p>

<p class="MsoNormal" style="margin-bottom:12pt">I've run over 150K miles on Champion plugs with nary an issue (and will continue to do so); RN12YC for the BJ8 and whatever the recommended is for a 100M (RN10C?). With Pertronix Ignitors in both, I run slightly over 'book' value (0.025") at 0.028" and both run very well (I also run stranded copper wire secondaries, so the 'R' is important, plus the plug caps have a resistor in them as well). My one-time auto shop teacher father maintained whatever spark was sufficient to ignite the mixture was adequate--mixture and compression took it from there--but a larger gap induces a 'hotter' spark which may be beneficial with leaner mixtures and at higher engine RPM (but has less margin as the electrode erodes). A larger gap requires the coil to produce more secondary voltage to jump the gap; a sports coil may be required to produce a consistent spark. 12K miles on plugs is fine in my experience--as long as the engine is in good nick--and they can be cleaned and re-gapped at least once. Sandblasting is a no-no as it will pit the ceramic insulator and can cause issues. <br><br>I came across a YouTube video by David Vizard where he claims E3 Diamond 'Split Fire' plugs produced slightly better mileage; yep, E3 makes a plug for Big Healeys (6-cyl only, I think). I've heard rumors that counterfeit NGK plugs are in the market.<br><br><br><u></u><u></u></p>
