[Healeys] Triple Weber 45DCOE Carburettors

[Don]

Derek,
FWIW, Weber's have a couple of distinct advantages over the SU in my
book.  They do not have jet diaphragms that are prone to leak.  The
float bowl is part of the carb and not separate.  Each throat is
adjustable to each cylinder.  My car is a lot easier to start cold with
the Weber's as well. Be aware that SU's when tuned properly can work as
well as any Weber setup.

1) No more adjustment than an SU.  Usually just have to remove and blow
out the jets if you notice any problems.

2) Depends on how the engine was set up and the cam plays an important
roll on any Weber installation.

3) Street drivability and mileage can be close to the same.

4) If it was done right, no need to change back to SU's in my opinion.

Hello again gentlemen.

I have been off the list for over two years since I sold my Healey when
I
moved to Malta. I now realise I can't live without one and I'm in the
process of buying another.

I'm currently interested in a well restored and uprated  100-Six that
has a
3000 engine which has had several interesting performance enhancements
to
make it into a 'fast road' or 'track day car'. I should mention that
whereas
my old car was a 'stock' concours style restoration this time Im looking
for
something different and in particlar I'm interested in the rally look so
this car could fit the bill.

However the car comes with triple 45DCOE Weber carbs and to be honest Im
a
bit apprhensive about these so id appreciate some honest opinions from
the
experts out there. I dont intend to race the car, but I will probably do
some long rallies and even perhaps some hill climbs so I intend the car
to
be more than just a sunday driver.

Some questions.

1. Once set up correctly do they need regular adjustment or are they
relatively stable. I will need an expert to set them up and therefore
don't
want to be having to pay somebody every two minutes.

2. Is it true that most of the power only comes in at the top end, ie
not
really useful if not racing, or does that depend on how they are set up
to
begin with. I understand that there are multiple variables in how they
can
be set up.

3. I imagine that fuel consumption could increase significantly. Any
thoughts? The engine  is currently rated in excess of 200bhp.

4 Would it be better all round to switch to triple 2" SUs. To be honest
I
doubt I will ever be able to set up triple Webers myself!

Any thoughts much appreciated.

BTW I did keep my 100 Six website online and will continue to update it
in
the future.
