Does it have spark?
Coil bad, or too much air gap? Spark plug gapped correctly?
Is it getting fuel?
You mentioned blowing in the tank and pouring fuel in -- it should start and run on what you put in the carb by bypassing the diaphragm.
Is it even trying to fire? Do you have compression?
Internal combustion engines require three things to run -- fuel, ignition, and compression.

Flywheel still indexed to the key? Valves opening/ closing (look in the spark plug hole)?
