for that. I’ll certainly bear it in mind.
Likewise, I’ll keep a close eye on my engine’s
temperature. The latter is quite well

baffles, 5 blade fan plus electronic fan. But,
as I said, I’ll keep an eye on it.</span></p>

[Healeys] Spark plug gap</span></p>
</div>
</div>
<div class=""> </div>
<div class="" style="margin: 0px;"><span class=""
style="font-size: 10pt; font-family: Arial,
sans-serif;">For me, i prefer Champion plugs
plugs to NGK, but that´s a matter of taste. I
think both, Champion and NGK, are of similar
quality. Matter of taste, as I wrote. But NOT
the car manufacturer determines the plug gap,
its the plug manufacturer. Definitely the car
manufacturer takes this for his specs in the
workshop manual.</span></div>
<div class="" style="margin: 0px;"><span class=""
style="font-size: 10pt; font-family: Arial,
sans-serif;">There is to much hype about plugs
anyway. I am working as a professional,
Elecrtonics and Elecrtrcian engineer, at a big
classic car parts supplier here in Europe and
I never go away from the given plug gap as set
by the plug manufacturer. Austin-Healey
engines are not high tech, they are tractor
engines and can take a lot of misfit, but
anyway BMC knew at the time what´s best to do
with them, even its printed 60 or 70 years
ago.</span></div>
<div class="" style="margin: 0px;"><span class=""
style="font-size: 10pt; font-family: Arial,
sans-serif;">Some people try to adjust the
fuel mixture with a CO-tester. You can do
that, but it doesn´t give best results for
road use, especially in hotter climates and
high above sea level. </span></div>
<div class="" style="margin: 0px;"><span class=""
style="font-size: 10pt; font-family: Arial,
sans-serif;">When you are very good in engine
engineering and have all the tools you can try
to find some more horsepower in your engine,
but you always pay that with some more heat
produced, which is not at all good for our old
BMC engines.</span></div>

<p class="MsoNormal"
style="mso-margin-top-alt: auto;
mso-margin-bottom-alt: auto;"><span class=""
style="font-size: 9pt; font-family: Arial,

gap was determined by the car’s
manufacturer ie one could expect to find
the same plug in two different cars and to
find that the recommended gap was not the
same for each car.</span></p>
<p class="MsoNormal"
style="mso-margin-top-alt: auto;
mso-margin-bottom-alt: auto;"><span class=""
style="font-size: 9pt; font-family: Arial,

suggests Champion plugs at 0.024” to
0.026” and that was some 60+ years ago.
I’ve always been told that Champion plugs
aren’t the best in the world and I’m sure
that a modern NGK can stand a little more
heat than the Champions that were around
60 years ago.</span></p>

<div class="" style="margin: 0px;"><span

class="" style="font-size: 9pt;
font-family: Arial, sans-serif;">I run
my MkII BT7 on NGK BP6ES which were

on this list.</span></p>
<p class="MsoNormal"
style="mso-margin-top-alt: auto;
mso-margin-bottom-alt: auto;"><span

mso-margin-bottom-alt: auto;"><span
class="" style="font-size: 9pt;
font-family: Arial, sans-serif;">Now,
talking of “recommended”, the rolling
road guys told me to set the plugs at
0.028” and pooh-poohed anything bigger

much greater gaps with my approximate

<p class="MsoNormal"
style="mso-margin-top-alt: auto;
mso-margin-bottom-alt: auto;"><span
class="" style="font-size: 9pt;

<p class="MsoNormal"
style="mso-margin-top-alt: auto;
mso-margin-bottom-alt: auto;"><span
class="" style="font-size: 9pt;
font-family: Arial, sans-serif;">The
other day, I decided to experiment and
set my spare set at 0.032”. Same NGKs,
no mileage on them..decent plugs.
Anyhow, it made a very surprising
difference. All round performance is
much enhanced.</span></p>
<p class="MsoNormal"
style="mso-margin-top-alt: auto;
mso-margin-bottom-alt: auto;"><span
class="" style="font-size: 9pt;
font-family: Arial, sans-serif;">Despite
it’s 3:54 diff and 28% OD, it was
never sluggish on our local hills. But
now it fairly zooms up them.</span></p>
<p class="MsoNormal"
style="mso-margin-top-alt: auto;
mso-margin-bottom-alt: auto;"><span
class="" style="font-size: 9pt;
font-family: Arial, sans-serif;">To be
frank, all a bit of a surprise.</span></p>
