clicks, wont crank ??? check ground first, then suspect a bad starter as long as the solenoid and battery are good... a 12v test light will help here

Usually, there is a hole plug near the bottom of the casing. BUT first drive it around a lot cause gear oil is heavy and it won't come out very fast if it is cold.

are you into troubleshooting? Probably not, but one must have fuel, ignition, and air to make things burn or run an ICE.
What don't you have?
Is there an ignition source? Did you pull the spark plug and verify it will spark?
Is there fuel? No, not in the tank, it must be getting to the engine.
Is the spark plug wet? If it isn't wet with fuel, you are not getting fuel.
Is there air? No, not what you are breathing, but getting to the carburetor. Did you check the air cleaner?

It acts like you have burnt spots on the starter shaft that touches the brushes ( voltage) to start. When you rock the vehicle in gear the starter shaft moves and it is placed in a position where the brushes can make a clean contact. Then when you turn the key, the starter will engage and the vehicle will start. My recommendation would be to change out the starter.

check wire harness for short

It sounds as though your ignition switch is not hooked up correctly. Follow the harness from the ignition switch to the bullet connectors under the front body plastic. Make sure the colors all match up.
