IVE READ MANUAL AND EVERYTHING SEEMS TO BE [ GO ]  I FOLLOW THE THROTTLE, CHOKE, DIRECTIONS BUT STILL ZIP. WHADDA YA THINK?

Answer
Sometimes there are safety interlocks that prevent the engine from starting.

Have you checked to see if you have spark?

Another test you can do is try using starting fluid sprayed directly into the carb throat.  If the engine trys to start then the problem is the carburetor.

Let me know what you find.
