<p class="MsoNormal">Hi,</p>
<p class="MsoNormal">I have been to Paris and, touch wood, was
able to help my nephew get his BJ8 up and running. In order to
arm myself with all the information that I could get hold of
I’ve asked you guys quite a few questions and been pretty
stingy with the thanks and feedback.</p>
<p class="MsoNormal">So:-</p>
<ol start="1" type="1">
<li class="MsoListParagraph">When we picked the car up at the
port, it was hard to start – unsurprisingly, I thought – and
it didn’t run very well. But it made the 100+ miles to
Paris, only really baulking when traffic slowed us down and
the revs dropped.</li>
<li class="MsoListParagraph">Subsequent to that, the car ran
badly…….erratic firing and then flat battery.</li>
<li class="MsoListParagraph">My nephew suspected the battery
and bought a new one. That went flat and the erratic
behaviour continued.</li>
<li class="MsoListParagraph">I suspected the generator and
inquired of the list regarding symptoms.</li>
<li class="MsoListParagraph">I also got my nephew to run the
standard “Does the generator work?” tests. It failed them
all.</li>
<li class="MsoListParagraph">About this time, the front carb
started to leak……nothing much, but the behaviour and
location of the leak pointed me away from the float bowl.</li>
</ol>
<p class="MsoNormal">Some background, maybe some clues. We’ll
never know:- there are often a stack of bits that come with an
old car. In this case, the stack was pretty big and, amongst
other things, was a new Indian RB340 Lucas lookalike Voltage
Regulator/Control Box. The car was fitted with another Indian
RB340 lookalike which looked brand new. That box was wearing
the original Lucas’s lid.</p>
<p class="MsoNormal">There were also a number of carb
bits…….seals, jets and so forth. Plus a few drum brake rubber
parts. Now, hindsight is a lovely thing, but – retrospectively
– one wonders.</p>
<ol start="7" type="1">
<li class="MsoListParagraph">I brought a new generator over
from the UK plus other parts and tools. Not easy these days
what with security at the airports etcetc.</li>
<li class="MsoListParagraph">We fitted the new generator. The
car started, “no charge” red light went off and engine ran
well for, say, a minute. Then, smoke from insulation on
large terminal on generator. I suspected polarity and/or
control box.</li>
<li class="MsoListParagraph">However, the attempts at starting
seemed to have turned the front carb’s leak into a flood.</li>
<li class="MsoListParagraph">More questions to you guys. I
suspected the diaphragm…..the sheer volume and location of
the leak pushed me in that direction and you all agreed.</li>
<li class="MsoListParagraph">So, a two carb rebuild kit was
ordered from the UK and, quite miraculously, turned up
within 18 hours.</li>
<li class="MsoListParagraph">Removed the carbs…..what joy.</li>
<li class="MsoListParagraph">The front diaphragm was dry and
split around the centre. The rear wasn’t much better, but it
wasn’t leaking yet.</li>
<li class="MsoListParagraph">Curiously, or so I thought, the
carbs showed some signs of being rebuilt, but rather
inconsistently and not the same parts in both carbs. But why
do the little bits and not the big one, the “Usual
Culprits”??</li>
<li class="MsoListParagraph">Anyhow, the rebuild worked and
the drip/flood stopped.</li>
<li class="MsoListParagraph">Back, finally, to the
generator…..not previously having liked the mix of frying
generator and spouting petrol.</li>
<li class="MsoListParagraph">We had no luck initially but,
after tidying up all the ignition wiring and polarizing the
generator we proceeded.</li>
<li class="MsoListParagraph">The generator still worked. It
passed the “Motor test”. </li>
<li class="MsoListParagraph">The wiring to the, just in case
polarized, Control Box was OK. So…..</li>
<li class="MsoListParagraph">We swapped the control boxes and
hey presto…..no red light, no smoke, no erratic running. ie,
everything they say about those boxes is true.</li>
<li class="MsoListParagraph">Thereafter, the car’s run well.
Starts first time and runs strongly once it’s warmed up.</li>
</ol>
<p class="MsoNormal">And, if you’ve read this far, thank you all
very much for your help.</p>
<p class="MsoNormal">Regarding not having a manual, I think
that, between us, my nephew and I are virtually into double
figures. I do the research, read the manuals, make up my mind
and then, before I make a catastrophic cock-up, I ask the
gurus. Can save a lot of time and, in this case, an airfare or
two!</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Now…… now, I think it’s leaking brake fluid
somewhere. In the servo somewhere is my guess. But the car’s
in Paris; my nephew’s in the South of France and I’m in the
UK. So, we’ll have to wait and see. It may be nothing, but I
wonder if the car, having sat around idle for ages, may have
dried out any number of seals and God knows what. We’ll see…..</p>
