Sounds like a backfire caused by a combination of a rich cold mixture and
overshoot of the metering flap caused by a rapid opening of the throttle. 
Control pressure is low when the engine is cold, and so the metering flap
will overshoot under a "spike" like this.  You are probably sending a big
shot of gas into the engine, causing a backfire that kills it.

Thoughts on this from the more F.I. knowledgable?
