My Lyc's plugs used to do that until I switched to hotter plugs. Also,
for taxi the mixture must be leaned almost to the point that the rpm
drops and taxiing must be done at no less than 1,000 rpm.

I don't even push the mixture all the way in on start anymore. I have
an IO540 so the start happens with the throttle cracked and the mixture
full lean. I just push it in about an inch with my thumb when the
engine starts to catch.
