This sounds very much like too thin of oil in the dampers, or no oil at
all.
The oil is what performs the equivilent function of an accelerator pump
on a normal carbie.
When the oil is cold, it tends to have a higher viscosity, and thus
seems
to work better.
If the oil is too thin, the venturi piston is allowed to move too
rapidly, and
the choking action of the dampers is insufficent to run the engine
properly.
Slowly opening the throttle reduces the need for the enrichment, so it
runs
better there.
I have experimented with various grade oils, in my strombergs, with
varied
results, but one thing I found was that multi-vis oils tend to give
varying
performance levels depending on the under bonnet temp.
I settled down with a simple single weight (20 wt) oil, and it seemed to
do well.
