Hello,<br /><br />I recently bought an old Eska 5 hp probably made in the very early '70's and need to know the spark plug gap and the oil/gas mix ratio for the motor.<br /><br />The only info I have is on the gas cap it mentions using 1/2 pint SAE 30 oil per 1/2 gallon gas. <br /><br />I would appreciate anyone who has this info to post it or e-mail it to me. Many thanks in advance!<br /><br />Gary
