Answer
Hello Dan:

From the Description, it Sounds like the Starter Gear May Need Replacing. Just to be Safe Lets Check the Starter, Starter Gear and Solenoid. Remove the Dust Cover from the Starter so you can Observe the Starter Gear in Operation and to Visiually Inspect the Starter Gear. Use your Jumper Cable Set and Attach the Positive Lead Onto the Positive Post of the Battery (make sure the Battery is Fully Charged or is a New Battery). Now Firmly Touch the Large Post on the Starter. If the Starter Does Not Turn, then the Starter is Bad. If the Starter Turns the Engine Properly, Then Check the Solenoid. Firmly Touch the Small Post at the Base of the Solenoid that has the Ign Wire Attached to it. If The Starter Does Not Turn and the Solenoid Clicks, Then the Solenoid is Bad.
