Float Level
- Ensure vehicle is on level ground. Start engine and warm to normal operating temperature. Snap throttle between idle and 3000 RPM several times and then let engine idle.
- When fuel level stabilizes, check that it touches center mark on each inspection window. If fuel level is higher or lower than mark, adjust by turning auxiliary and/or primary/secondary float external adjusting screws. See Fig 1 .
- When correct float level is achieved, paint adjusting screws with White paint to aid visual inspection of adjustment screw locations and to help prevent adjustments from changing.
