- 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.
