How do you rebuild a craftman II/523 snow blower carburator?
If it starts up with starting fluid, the first thing that I’d check would be the spark plug. The plug might just be fouled out. A cleanup with some fine sandpaper would handle that if you can’t get to a parts store for a replacement. The nice thing about Craftsman products is the fact that Sears’s parts department is awesome. You can call them up with your same question that you posted here, and they can tell you if they have the part on the shelf. If they don’t have one in the store, they can get you one in a day or two. Personally, I’d call them up and ask for a replacement carburetor, unless you have the saintly patience required to actually rebuild one. If you want to rebuild it, they can hook you up with a kit and instructions.
