Hi everyone,<br /><br />I have a Sea King made by Clinton from Montgomery Wards and(model year unknown) have searched this great site over a few times and have not seen my exact engine to find out the fuel mixture. I understand that if it is an air cooled engine I should use regular weed wacker two stroke oil, and if it is watercooled I should use TCW3 oil. If anyone has any info on this engine regarding fuel mixture, spark plug type, parts, or anything else, it would be great to know, Thanks!!<br /><br />Engine model: K750 3110D<br />Type: XTV 52259<br /><br />Mike
