Spray some starter fluid in the air filter. If you don't have any
starter fluid, carburetor cleaner works as well with the added benefit
of cleaning the throttle body.

This is good advice...if you want to blow-it-up! (and don't tell me
you've done it dozens-of-times)

Use WD-40 directly into the open throat of the carb. It adds lubricant
and the propane (used as propellant) gives the pop.

Ask any small engine mechanic.
