Cleaning your carburetor
Soak your carburetor parts in carburetor cleaner. Some cleaners will discolor your carburetor, so follow instructions. Wash all chemicals off with hot water, blow out passages with compressed air. Ethanol will leave residue behind that cleaners will not get out so run thin wire through all small passages, especially on the venturi cluster.
Polish your accelerator pump well so that the pump cup glides smoothly.
Even the best quality parts will fail if the ethanol gets in high enough concentration. Use Startron with your fuel to help with this.
