Why do mowers have primer bulbs?

seems simple enough.
a bulb is cheaper.
bulb requires fewer parts in the carb. fewer parts mean less cost.
craftsman have bulb. cheap
Honda does not have bulb. not cheap

Poor mainframe can't get an answer to his question.
Here ya' go. The old carburators allowed the heat of the day
to push fuel through the engine when not running. This fuel
evaporated into unnecessary pollution. It would also (sometimes)
flood the engine and make it hard to start. The new carbs, in order
to comply with emissions standards, do not allow this fuel to be
pushed through. In exchange for that, you need to prime the
engine with the bulb.
