Sears 9hp Ted Williams (fuel-oil Ratio?)

[cjartist]

I have a Sears 9HP Ted Williams model # 574-59740<br />SN 68600910-2383. Does anyone know when this was made and what the fuel-oil ratio should be? Also anyone know where I can get parts?

You have a McCulloch built motor 68-70.<br />Fuel mix is 50:1.Some parts may be available at<br />NAPA.But I have heard they are dropping their Marine products line. And some branches never did<br />anything with marine products. Sierra products should have the parts.You could watch Ebay for parts and ask at the antique outboard motor club<br />at: www.aomci.org.

I have the original owners manual for my Dad's '67 Sears Ted Williams 9hp and although the manual doesn't list the ratio, it says to mix 1 qt of oil to 10 gallons of fuel. That comes out to 40:1 ratio. My Dad, however, was using a mixture of 2-1/2 oz of oil and 1 oz of lead to 2-1/2gallons of fuel. Seems a little lean on oil, but has worked the last 40 years or so.
