Hello:

When one pumps the bulb the few times that is required when starting the
typical lawnmower, etc.,
exactly what is one doing ?

a. e.g., does the pumping action just draw gas into the bulb, and then the
next push on the bulb
squirts it into the carb, or... ?

b. If there is gas in the bulb, can one consider the engine "primed" ?

If someone might explain this bulb pumping routine a bit, and exactly what
happens,
would be appreciative. Realize I really don't understand what is happening

Thanks,
Bob

Pull off the air cleaner and take a look down the carb while pressing
the primer bulb and see what happens. You'll see the gas squiring
towards the engine intake.
