D. Install Jet Mixture Solenoid

1. Remove the jet mixture solenoid valve (Figure 9).

2. Insert the new jet mixture solenoid valve and hand tighten it.

CAUTION:
If the solenoid threads seem to bind when tightening by hand, do NOT use force. Loosen and retighten to remove burrs and avoid crossthreading.

3. Place the provided 13 mm JMS tool on the provided inch-pound torque wrench.

NOTE:
The JMS tool must be at a 90~ angle to the torque wrench to assure a correct torque reading.





4. Tighten the jet mixture solenoid to 26 in.lbs. torque (Figure 10).

NOTE:
Do not over tighten the jet mixture solenoid valve since this will distort the valve and cause an over rich condition.

5. Connect the jet mixture solenoid electrical connector.

6. Inspect the carburetor to determine if the concealment plug at the idle mixture adjusting screw (MAS) was previously removed and not reinstalled. If the plug is missing, skip steps 7 through 9. If the plug is present, proceed to step 7.

7. Clamp the carburetor in a vise with the idle mixture adjusting screw (MAS) facing up. (Make sure to protect the gasket surface from the vise jaws.)





8. Drill a 5/64 in. (2 mm) pilot hole in the bottom area of the casting surrounding the idle mixture adjusting screw (MAS), then redrill the hole to 1/8 in. (3 mm) (Figure 11).

9. Insert a blunt pin punch into the hole and drive out the plug.

10. Reinstall the carburetor using the Service Manual procedure. Use a new carburetor gasket from the Emissions Service Parts Package.

11. Reinstall the throttle return spring.

12. Refill the radiator coolant.
