[Healeys] Starting a BJ8

[Bluehealey]

I think it's a feature of those 2" carbs.

The air speed across the jet is quite low at cranking speed, much lower than
with HD6's as the 8's have 30% larger choke area for the same volume of air
being pulled by the induction.  As a result there is a need to get the jets
pulled as low as possible to get fuel into the throats.

The starter fluid trick seems to confirm that.

I live on the coast of the southern USA where winters are very mild.  My
carbs and everything else are adjusted properly, but still my BJ8 is hard to
start when it has been sitting for more than a few days -- even in the
summer.  I have heard discussions before from people on the list about how
their Healeys are hard to start, so I think it is a characteristic of the
engine (assuming all adjustments are correct, of course).  The engine will
start eventually, after multiple tries.  But if I just give both carbs a
shot of starting fluid after filling the float bowls, then jump in, pull the
choke full out, and turn the key he engine starts immediately, without all
that grinding on the starter.  Starting fluid is cheap. Rebuilding the
starter not so much.

 

There is no accelerator pump on the SU carburetors to provide a rich mixture
for starting, so "pumping" the accelerator pedal only opens and closes the
throttle plates and does nothing to help the engine start.

My nephew has just recently acquired a very nice BJ8 which he imported from
the US to France. Some of you may recall being asked for and kindly giving
advice re vendors and cars etc.

Now, the car is safely tucked up in a garage in Paris and all is well......

Except.....except - there's always an "except" or a "but" isn't there? -
except, it doesn't really like starting. It needed a new battery which we'd
been told to expect but, even with that, it's a little slow to fire up. 

10+/- attempts my nephew said.

Now, I'm in England; the car's in France and my nephew would be the first to
admit that he's never been a mechanic or owned a car remotely like a 3000.
So, it's very likely that his technique needs polish!

(The fuel pump works; fuel get to the carbs. The ignition seems good and
will soon be better (in my own humble opinion) with a Pertronix EI and a
"Flamethrower"(?) coil.

Leaving aside any worries as to potential problems with fuel or spark for
the moment:-

How do you guys start your BJ8s???

One pump? No pump? Choke and foot half down?

What do you do if it fires then goes dead again?.....give it a little pump
when it coughs, then ease off?

Yes, we know that they're all a bit different as are we, but I'm trying to
establish a start point. (No pun intended!)
