so that they may be seen.
3. Run the engine until it reaches no rmal operating temperature, then shut
off the engine.
4. With the ignition OFF, connect a ta chometer to the distributor, and a
timing light with an inductive pickup lead to the No. 1 spark plug wire.
WARNING - Never pierce a secondary ignition wire in order to connect a timing
light. A pierced wire may lead to engine misfiring and driveability problems.
5. To properly set the ignition timing , the EST must be placed in the bypass
mode. a. On the 2.5L engine, refer to t he emission control label for the
procedure.
If the label is missing or unreadable, c ontact your Chevrolet dealer for a
replacement.
b. On 2.8L and 5.0L ca rbureted engines, disconnect the 4-wire EST
connector at the distributor. (Fault code 42 may be set in ECM memory,
and must be cleared once the procedur e is completed). Proceed to Step
7.
c. On 2.8L, 5.0L and 5.7L fuel inje cted engines, with the engine RUNNING
and all accessories off, use a jumper wire to connect diagnostic terminal
B and ground terminal A of the 12-terminal Assembly Line Diagnostic
Link (ALDL) usually located under t he left side of the instrument panel.
DO NOT disconnect the 4-wir e EST connector at the distributor. Aim the
timing light at the timing mark; the li ne on the balancer or pulley will line
up with the timing mark. Increase engine speed and check for timing
advance. If the timing still advances with engine speed, perform Step 6. If
timing does not advance with engi ne speed, proceed to Step 7.
If timing advances with engine speed, it will be necessary to disconnect the
single-wire Set Timing connector. (Faul t code 42 may be set in ECM memory,
and must be cleared once the procedure is completed).
6. Remove the jumper wire from t he ALDL, and shut off the ignition.
Disconnect the Set Timing connector, usually located under the plastic
cover above the heater unit, in the engi ne compartment. (The wire in this
connector is normally Tan/Black.)
7. With the engine running and all accessories off, aim the light at the timing
mark. The line on the balancer or pulle y will line up with the timing mark.
If a change in timing is necessary, loosen the hold-down clamp bolt at
the base of the distributor . While observing the timing mark, rotate the
distributor slightly unt il the line indicates the correct timing. Use the
timing specification on the emi ssion control label in the engine
compartment. If this label is missi ng or damaged, refer to the Tune-Up
Specifications chart in this Section.

REMOVAL & INSTALLATION
Always replace all internal gaskets that are removed. Flooding, stumble on
acceleration and other performance comp laints are in many instances, caused
by presence of dirt, water, or other foreign matter in carburetor. To aid in
diagnosis, carburetor should be carefully removed from engine without draining
fuel from bowl. Contents of fuel bowl may then be examined for contamination
as carburetor is disassembl ed. Check the fuel filter.
ROCHESTER E2SE 1. Remove air cleaner and gasket.
2. Disconnect fuel pipe and vacuum lines.
3. Disconnect electrical connectors.
4. Disconnect accelerator linkage.
5. If equipped with automatic transmi ssion, disconnect downshift cable.
6. If equipped with cruise c ontrol, disconnect linkage.
7. Remove carburetor attaching bolts.
8. Remove carburetor and EF E heater/insulator (if used).
9. Inspect EFE heater/insulator for damage. Be certain throttle body and
EFE heater/insulator surfaces are clean.
To install: 10. Install EFE heater/insulator.
11. Install carburetor and tighten nuts alternately to the correct torque.
12. Connect downshift cable, as required.
13. Attach the cruise cont rol cable, as required.

9. Connect one end of the other jumper
cable to the negative (-) terminal on
the booster battery and the final cable clamp to an engine bolt head,
alternator bracket or ot her solid, metallic point on the engine with the
dead battery. Try to pick a ground on the engine that is positioned away
from the battery in order to minimi ze the possibility of the 2 clamps
touching should one l oosen during the procedure. DO NOT connect this
clamp to the negative (-) term inal of the bad battery.
CAUTION - Be very careful to keep the jum per cables away from moving parts
(cooling fan, belts, etc.) on both engines.
10. Check to make sure that the c ables are routed away from any moving
parts, then start the d onor vehicle's engine. Run the engine at moderate
speed for several minutes to allow the dead battery a chance to receive
some initial charge.
11. With the donor vehicle's engine still r unning slightly above idle, try to start
the vehicle with the dead battery. Crank the engine for no more than 10 \
seconds at a time and let the starter cool for at least 20 seconds between
tries. If the vehicl e does not start in 3 tries, it is likely that something else
is also wrong or that the battery needs additional time to charge.
12. Once the vehicle is star ted, allow it to run at idle for a few seconds to
make sure that it is operating properly.
13. Turn ON the headlight s, heater blower and, if equipped, the rear
defroster of both vehicles in order to reduce the severity of voltage spikes
and subsequent risk of dam age to the vehicles' electrical systems when
the cables are disconnected. This st ep is especially important to any
vehicle equipped with computer control modules.
14. Carefully disconnect the cables in the reverse order of connection. Star\
t with the negative cable that is attached to the engine ground, then the
negative cable on the donor battery. Di sconnect the positive cable from
the donor battery and finally, disconnect the positive cable from the
formerly dead battery. Be careful when disconnecting the cables from the
positive terminals not to allow the alli gator clips to touch any metal on
either vehicle or a short and sparks will occur.
JACKING
Your vehicle was supplied with a jack for emergency road repairs. This jack is
fine for changing a flat tire or other s hort term procedures not requiring you to
go beneath the vehicle. If it is used in an emergency situation, carefully follow
the instructions provided eit her with the jack or in your owner's manual. Do not
attempt to use the jack on any portions of the vehicle other than specified by the
vehicle manufacturer. Always block the diagonally opposite wheel when using a
jack.
A more convenient way of jacking is the use of a garage or floor jack. You may
use the floor jack to raise the vehicle in the areas shown in the illustration .
