They were made by the Lauson corp. that was bought out by Tecumseh back in 1957-8. The motors were made between the years 1940-1957. Four stroke, air cooled and one or two cylinders. They didn’t need a water pump for cooling. You do need to make sure there is oil in the sump, (30w, non detergent}. You don’t need to add oil to the gas. The points are gapped at 0.020″. If the points are clean and gapped, oil in the sump, carburetor cleaned, and grease in the gear box, the motor should run well. There are lower covers that should be installed as it aids in cooling the motor.
