Did that today...
Replaced fuel lines, Cleaned tank, added a new filter (air and fuel), rebuilt carb.... Still done the same thing..... But, as soon as it went dead i jumped off the mower and checked the spark again, and the spark was orange, not blue!
Spark color determines virtually nothing. The hottest spark is ultraviolet which we can't see. Blue spark is cold in comparison to ultra-violet. Orange and yellow come from particles of sodium in the air ionizing in the high energy of the spark gap.
