Unfortunately, a service manual is not going to be easy to find. You may be able to order from Powermate, but you may want to save your money and spend it on consumables.
I am guessing that you are looking for a service manual for the engine itself? Good Luck on that one as well, as Tecumseh has folded. Post the engine model# and other information found on the tag, somebody (perhaps myself) may have the manual you need and send it to you via email.
Parts for the engine itself are likely to be hard to find, consider an engine replacement. It likely will be cheaper.
