My injected 360 does that too, more so in the winter.  My mechanic says it is
because of the extra fuel used getting it started in cold weather.  And it
clears up when the temps come up (like higher power settings for take off).
Sometimes it will clear up if I lean agressively with high power during the
ground runup.
