You should be able to get the manual from Sears parts web site for free download. You will need the nine digit model # with the decimal after the third digit. Beware their parts are extravagently priced plus shipping. Try to find an after market part, their are a lot of them. Your local small engine shop has several catalogs frrom several sources. Generic items got to a hardware store such as Ace or TrueValue. I have many Sears products and that is what I do.
