I have had the same motor for about 25 years and haven't started it for about 20 years. I went out yesterday, cleaned the carburetor and spark plug, put new gas in it and after about 10 pulls it started up and ran good.
I would also like to know what year it is so if you have found out please let me know. Would also like to know if the motor has any value.
Years ago Don Wiggins offered reprints of operating instructions and parts list for Wizard 2hp air cooled model.
I do not know if Don or a successor offers them today.
Perhaps an inquiry on AOMCI Ask A Member would be helpful

WBA West Bend Aluminum 6800 1968 model year seem likely
