Use the small hole on the starter cone, set throttle to about 1/4 open, prime the engine by covering the muffler output with a finger and turning the engine over a few times (by hand, keep the plug igniter OFF!), you'll see/hear the fuel when it gets to the carb.

Turn the engine backwards until you feel compression, place the glow igniter on the plug, place the starter cone FIRMLY against the prop nut and hit the starter button. (I highly recommend against getting the starter spinning and bumping it against the prop nut. Not good for engine or starter.)

The engine should start within one or two revolutions. If not, grasp the prop FIRMLY! and turn it counterclockwise through one compression stroke. You should feel the engine "thump". If so, it has fuel, it has a hot plug, and it's getting air. Try the starter again.

If you didn't feel that "thump", then you most likely didn't get enough fuel to the carb. Try priming it again. But be careful. It IS possible to flood the engine, in which case it can "lock up". Trying to spin it over in this condition can result in a broken connecting rod or other nasty damage. (More of a problem with an inverted engine though.)

Good Luck,
