There has been some confusion about how to measure the float level. The float used to have a small dimple on the tip of the float, which was used for the float level measurement. That dimple is generally missing. Simply use the tip of the toe as illustrated in the instruction sheet.
Cleaning - Soak all parts in a bucket of carburetor cleaner (any brand from parts store) for 24 hours, wash with hot water (remove all chemical). Blow out passages with compressed air. Run thin wire through all of the passage ways. Ethanol leaves residue in the passages that cleaners will not get out. Leave out any rubber part that isn't going to be replaced.
