Scot:
Here is what I do (BJ8): At cold start (even in warm weather) pull on the
choke, start the engine and while feathering the throttle slightly,
immediately move the choke knob part way in to leave a small amount of
enrichening and fast idle in play for a few minutes. Then, push the knob in
a bit more in an appropriate amount of time to leave a bit of fast idle, but
no choke - then all the way in when it's suitable. The original choke cable
has a twist-lock provision at the knob to permit this.
A bit of experimentation will give you the idea quickly. This procedure
assumes that the whole carb set up is correct or very close to it -
mixtures, synchronization, etc, and that the ignition is set correctly.
Your description tells me that your car is probably very close - it starts
quickly, but is immediately a bit rich. This seems to be the pattern for
most well tuned BJ8's. In very cold weather, you would have to leave it
choked for longer - more time between the steps.
These are Healeys - one must learn their idiosyncrasies and beat them at
their own game! Call it part of the 'mystique'.

>My experience is that on a completely cold engine, (overnight) if it
will start without a choke, the mixture is a bit too rich. Maybe the jet
adjusting nuts could be leaned a bit or the choke linkage isn't
completely releasing. (Jets not returning to their full up position
when the cable is released.) Not a serious problem as long as you are
happy with the way it runs.

Dave,
Along these same lines,my BJ8 will not start without choke, however, I do
not think it is adjusted correctly and am not happy with the idle as the
engine warms up.
Frankly, this basic adjustment is somewhat of a mystery to me and I do not
know how to correctly adjust my choke. I am familiar with the slow idle and
jet adjusting screws.
Could you or someone on the list be instructive concerning choke
calibration?
Currently, when I have full choke applied on a cold engine it coughs and
sputters barely maintaining 1000 RPM with noticeable black smoke out the
back! This transitions to a nice idle and no smoke as the engine warms.
Any tips greatly appreciated.
