Cleaning:
  • Soak your carburetor parts in a 1 gallon can of carburetor cleaner bought from your favorite parts store. Be sure to follow the directions on the can, otherwise you may damage the carburetor color.
  • Wash off all chemical with hot water.
  • Spray carburetor cleaner through each passage to make sure they are clear.
  • Use our nylon cleanout brush set to further clean any passage.
