There are dozens of brand of lawn edgers that are available too purchse. One of the best is Craftsman,another good brand is Honda.

Champion CJ8 spark plug is for the crsftsman 3.0 edger/trimmer
I recommend adding it to the oil tank.
The belt that you are looking for is a Sears V-Belt, Part No. 32668
The oil drain plug is located on the bottom of the engine underneath the edger. It takes 20 ounces of SAE30 weight oil. I recommend you use synthetic oil in any air cooled engine. Change the oil every 25 hours. Click the link to download an owners manual.
The best brand can be debated, but most reviewers give the Troy Built gas powered TBE515 rave reviews. You can also purchase a battery or electric edger, or simply see if your current string trimmer can accept an edger attachment.
1/2x33 inch belt, manual calls for a 1/2 x32.60
I question your cc's, but a 30W of SG or greater rating should suffice.
A carburetor for the Craftsman Edger model 536-871200 can be ordered through any Sears store. These stores do not sell the parts inside the store, but can order the correct part through the catalog.Ê
