I traded off my old VW bug and got money and a boat with 3 motors with it. The one I think is newest is the 7HP Sea King. It has no stickers on it but on the bottom of the motor it shows: 70/2/6 which I would guess is the year of the motor. Aplying carb cleaner in it ,it fired up for 2 seconds. It has no gas tank but the fuel line connector going to the carb. Any idea what oil mixture I should use with the gas? Thanks in advance and I hope this is the correct forum for this message.
