Firey Stove

I was looking at a four burner gas stove.  I noticed the pilot light was very high.  I lifted the top of the stove off and all the burners were burning very high with a yellow flame.  Also the pilot lights were burning high with a yellow flame.  Where the gas line connects to the stove there was a leak and it burned with a small blue flame.  I put the cover back on the stove and left.
