Start with the basics. You need air, fuel, spark and compression.

Verify the spark plug fires when the threads are grounded to the engine somewhere.
Make sure there's gas in the tank, and the carb bowls have some in them as well.
Make sure the air filter isn't clogged.
Verify there's compression (using a compression tester)

Hopefully it's something silly like being out of gas!
