If I'm not to late on this, I'll take a WAG at it -

If I recall correctly, the rear fuel bowl on the Triumph 2000/2500 is 
mounted 1/8 - 1/4" higher than the front fuel bowl (I'm not sure about 
the Volvo and others).  To compensate on the TR6, the float would have 
to be adjusted down by this amount which would be challenging to do 
(especially with the fixed type float).  Normally the float would be in 
a horizontal position when shutting off the fuel and would be pressing 
vertically up on the valve.  Dropping the float down to compensate would 
cause the float to shut the valve in a less than horizontal position 
causing more side load on the needle and might cause the needle to stick 
and lead to flooding problems.

I was less than successful in my early attempts to do that on my car. 
Once I changed the bowl to the correct one (which did come from a Spit), 
no more flooding problems.

Hope that make some sense -

    When I did my SU conversion on my 75 TR6 my original front Cable was 
able
to link up fine
with the front Choke (enrichment Lever). I left the rear cable to perch
itself in front of the rear Carb
to look like it was actually doing something.

    While the subject of fuel Bowls was brought up in the context of this
conversion, there seems to be some
controversy as to the necessity of changing them to the AUD2140 (Spitfire)
bowl when doing them. Other than
just getting them to sit upright, I've heard contrary opinions from 2
different SU guru's. My AUC1310 Bowls,
as used on TR4A's and Volvo's were just swapped from one end to the 
other to
get them vertical and seem to run
fine with the BAE needles and K&N Filters. The other school of thought is
that they're both sitting too high and can alter
mixture over the range of the Metering Needles travel. Anyone else heard
anything on the subject. I'm rebuilding a set now
with the Spit Bowls, but I don't understand why it's necessary.
