Answer
 Hello Bruce:

 If you Clean the Crankcase and Fill with Fresh Oil and Have gotten all the Grit and Grime Out from Under the Blower Housing, then you should be Ready to add Fresh Gas and Start the Engine. Once Started, Run for 5 Minutes and then Shut Off. Let Set for 5 Minutes and then Drain the Crankcase Oil. Replace with Fresh Oil. The Plug Number in Autolite is: 4265
Hope this Helps. Let me know what Happens, Please.

 Good Luck

 Respectfully
