Refurbishment Process
Each carburetor is fully disassembled and chemically cleaned. Critical wear components are replaced using ethanol-resistant materials—including Viton seals and chemical-resistant well plug epoxy. After reassembly, units are flow bench tuned to provide consistent fuel delivery and smooth operation. Fine-tuning may be required based on engine wear, altitude, and modifications.

Tech Notes
Always purge fuel lines before installing any carburetor. Unflushed fuel lines can introduce rust and contaminants that damage freshly serviced units. Most carburetor issues post-installation stem from immediate contamination during initial float bowl filling.
