Engine turns over, won't start?
Do you have fuel to the carburetor?
Remove spark plug and with it grounded, see if you have spark.
If it has spark, put teaspoon of fuel into the spark plug hole, re-install the spark plug and see if engine will fire for a few seconds.
If it does, the carburetor needs to be removed and cleaned.
