CLEANING
Soak all parts except rubber and electrical in a carburetor dip. You can use any parts store product. We like using Simple Green but don’t let the parts soak more than 2-4 hours, or the parts could get discolored.
Wash (with hot water if possible).
Blow out all passages. Use your finger to feel air coming out of the opposite end to be sure the passage is clear.
Inspect parts for a worn condition, or any cracks.
