Disassembly
1. Disconnect the vehicle’s battery.
2. Remove the gas cap.
3. Drain approximately one (1) quart of engine coolant.
CAUTION: Hot water may be present.
4. Using either the map inside the vehicle’s engine compartment, or a factory service manual
for your year/make vehicle: tag each hose, vacuum line and electrical wire/connector
attached to the original carburetor and air filter assembly for proper identification during
reassembly. Disconnect all connections once they are identified.
5. Disconnect and remove the flexible connector and the sheet metal elbow between the
carburetor and the air cleaner housing.
6. Disconnect the fuel line from the original carburetor.
Plug the end of the fuel line to prevent leakage.
7. Disconnect the throttle cable from the throttle lever and the cable bracket.
8. Remove the four (4) nuts that secure the carburetor to the intake manifold. Remove the
carburetor and the spacer/gasket. Insert a clean rag into the intake ports to prevent dirt
and gasket material from entering the engine.
9. Remove the stock carburetor mounting studs from the intake manifold. NOTE: For correct
stud removal or installation, use stud removal/installation tool or the “double-nut” method.
DOUBLE-NUT METHOD: Install two nuts approximately half way down the stud. Lock the
nuts together. Turn the lo
wer nut for removal and the upper nut for installation.
10. Clean the intake manifold flange surface thoroughly.
ASSEMBLY
11. Remove the rag from the intake manifold.
12. Apply Loc-Tite (supplied) to the 8mm end of the stud into the two holes of the manifold
closer to the passenger side fenderwell.
13. Using appropriate gasket sealer, slide the smaller of the supplied adapter gaskets over the
two studs so that the larger hole is closer to the valve cover.
14. Slide the manifold adapter over the two studs in the same manner as the gasket and using
Loc-Tite (supplied) on the tow allen bolts supplied secure it to the manifold.
Torque the bolts to 7 ft/lbs.
15. Install 8mm studs into threaded holes of the manifold adapter (apply Loc-Tite to the studs)
insuring that the studs go no further than flush with the bottom of the adapter.
16. Slide the remaining gasket over the studs (with the large hole facing the valve cover), fol-
lowed by the Weber carburetor (insuring that the linkage faces the firewall). The AntiBackfire Valve bracket may require bending for clearance.
17. Slide the supplied cable bracket over the two (2) adapter studs closer to the valve cover.
18. Using the nuts and washers supplied, secure the carburetor to the manifold and adapter;
and tighten, in a criss-cross fashion to 7 ft/lbs.
