Rebuild planning and parts check
A carburetor rebuild works best when the parts are checked against the carburetor before any disassembly starts. Keep components sorted by location, and photograph the linkage and float setup so reassembly is accurate. Old gaskets, diaphragms and worn springs are the usual causes of a rebuild that does not hold.
Cleaning matters as much as replacement. Use a carburetor cleaner suited to the metal and rubber parts, and clear every passage with compressed air rather than wire, which can enlarge a metering orifice. Once the carburetor is assembled, confirm the throttle linkage moves freely before installing it on the engine.
- Work on a clean, well-lit bench
- Label screws and springs by location
- Replace gaskets rather than reusing them
- Blow out passages with compressed air
