How long have you been at this hobby? Just kidding.
The flywheel will start to spin as soon as the engine is started. Once the engine gets up to speed (as in more rpms caused by throttle inputs) the flywheel will cause the clutch shoes to spread and engage the clutch bell...this in turn engages the spur gear. Once the spur gear gets up enough rpms the tranny will engage.
As mentioned above, you may have some extra throttle input caused by a trim setting on your radio. This will cause the engine to idle at a much higher rpm. If the trim is neutral, and the engine is still idling high...you will need to adjust the idle set screw.
This is best done with the engine off and the air filter removed. Look down the neck of the carb. With the throttle at neutral (closed position) you should see about a credit card thickness (1-2 mm) gap in the carb. If this is not the case, adjust the idle set screw until you see this gap.
From there it is up to how you desire to set your idle. Some do not recommend using the Trim setting on the radio to adjust the idle as this affects the overall throttle throw. Others recommend adjusting linkage and throttle settings via the linkage. I will say that either way can and often does work just fine.

Well said Mr. Sky, as always. I think Pissant may have misconstrue the clutch bell with the fly wheel, no?
