First thing remove the spark plug, reconnect to the wire, and then ground the plug against the engine and then crank the engine to check for spark. If you have spark, then dump a small amount of fresh fuel in the spark plug hole, reinstall the plug and see if it starts. If no spark the we will have to do some further testing. If it starts and then dies, then you will need to remove and clean the carb, or depending on cost just replace the carb, it may be cheaper.
the other thing is next time just post in one location. It makes it difficult to follow the responses since people will be trying to answer your question in all the posted threads
