Warwick, I don't think there are kits for the Kirby-Lauson, or Lauson, engines but various individual parts are often available. Try the Outdoorking online store, and Tecumseh and Lauson on US sites for new parts. Try Outdoorking members or local mower wreckers for second-hand parts. I believe few if any parts are different between the Lauson and Kirby engines. Kirby didn't even make all the parts, just enough to get it classified as Australian-made so there wouldn't be import duty on the imported parts.
