Idle Mixture
Choke Cable Adjustment
Adjust the fast idle or "starter interlock", so that when the choke is engaged, it forces the throttle plate open slightly.
- Squeeze the choke lever as shown (nozzle will move down). The yellow connecting link will force the throttle open slightly.
- Measure the throttle plate opening
- 0.6 mm
- Adjust the amount of opening by bending the link.
Throttle opens by 0.6 mm ( measured between edge of plate and throttle bore)
Float Level Verification Check
To check the float level, attach a sight glass to the drain plug.
- Remove drain plug. Catch gasoline in a cup.
- Take a 5/16" hose L-fitting. Fit clear 30mm plastic tubing pointing up, and jam the fitting into the drain hole. Make sure it is secure. Position it parallel to the bowl (straight up/down).
- Nissan had a tool for this, number ST19200000 "Float level gauge"
- Start the engine and let it idle.
- Measure the level of fuel in the tube
- 22-24 mm from fuel bowl gasket
- Adjust float if too high or too low
Float Level Static Adjustment
When replacing the float level needle and seat, set the static level of the float.
- Remove Float Chamber cover
- Place it upside down and level
- Level from top of brass lever to flange (without gasket) should be:
- 11-12 mm
- If needed, adjust lever by carefully (and slightly) bending inner tab of brass lever.
