  We present 1.2 mm continuum images and spectral line observations of CO(1--0)
and SiO(3--2) rotational transitions of the recent nova V4743 Sgr. The nova is
detected at 1.2 mm showing a variable millimetre emission. Only upper limits of
T_A* = 0.06 K for CO and T_A* = 0.03 K for SiO could be derived. We discuss the
results in terms the nature of the millimetre emission favouring dust from a
phase before the recent outburst as the likely radiating source. We also
comment on the possibility of free-free emission from the ionised shell as the
source of the measured millimetre radiation.
