    Welcome Magnus.

    Following is for a 1940 Sportsman. Some may not be accurate for your 1939.

    Bore 1-3/4″ Stroke 1-35/64″, Displacement 3-3/4″, 2hp @ 3500 RPM. Prop dia and pitch 7″ x 6″ 2 blade. Breaker point gap 0.020″. Spark plug Champion H-10-J (H-10-C). Gap 0.025″. Shear pin 3/16″ x 15/16″ Aluminum. Weight 23-1/2 pounds. Oil 1/3 pint per gallon. Originally spec’d SAE-40. Water Cooled.

    Now you can have fun converting all that to Metric.
