I have a Stihl FS480 with a C1Q-S94 carburettor. You list 2 repair kits on the assembly diagram page: 4128 007 1060 and 1129 007 1062. Which is the correct one, or are they the same?

Stihl replaced the C1Q-S94 with another carb, because of this the gasket sets are different. The gaskets will depend if you have the Smoother connector or the Barbed connector. https://lsengineers.zendesk.com/attachments/token/nMGbF1My5c8b0XYaVgkfKRE0Q/?name=Technical+Information.pdf
