CHEVROLET CHASSIS SERVICE MANUAL

ENGINE 6-25

refer to Section 6 of the Chassis Overhaul Manual.

Because of the interchangeability and similarity of

many engines, engine sub-assemblies and engine parts,

regardless of which passenger vehicle they are used in,

typical illustrations and procedures are used except
where specific illustrations or procedures are necessary

to clarify the operation. Although illustrations showing

bench operations are used, most single operations, when

not part of a general overhaul, should be performed (if

practical) with the engine in the vehicle.

GENERAL DESCRIPTION

Various carburetors (fig. lc) are used with Chevrolet,

Chevelle, Chevy II, Camaro and Corvette passenger

vehicles. These carburetors are designed to meet the

particular requirements of engines, transmissions and

vehicles, therefore carburetors that look alike are not

always interchangeable. (Refer to carburetor part num-

ber and/or specifications.)

Because many service procedures for the various

carburetors are similar, typical illustrations and pro-

cedures are used except where specific illustrations or
procedures are necessary to clarify the operation.

This section covers removal, installation and adjust-

ments (on engine) of carburetors. Also covered in this

section are maintenance procedures for choke coils,

throttle linkage and fuel filters. For carburetor .over-

haul procedures and additional adjustments (bench), re-

fer to Section 6M of the Overhaul Manual under the

carburetor being serviced.

Specifications for carburetors are located in the back

of this manual.

SERVICE PROCEDURES

Preliminary Checks

1.
Thoroughly warm-up engine. If the engine is cold,

allow to run for at least 15 minutes.

2.
Inspect torque of carburetor to intake manifold bolts

and intake manifold to cylinder head bolts to exclude

the possibility of air leaks.

3.
Inspect manifold heat control valve (if used) for free-

dom of action and correct spring tension.

Idle Speed and Mixture Adjustment (Except Air Injection

Reactor System)

NOTE:
This adjustment should be performed

with engine at operating temperature and park-

ing brake applied.

1.
Remove Air Cleaner.

2.
Connect tachometer and vacuum gauge to engine, then

set hand brake and shift transmission into neutral.

3.
As a preliminary adjustment, turn idle mixture

screws lightly to seat and back out 1-1/2 turns.

CAUTION: Do not turn idle mixture screw

tightly against seat or damage may result.

4.
With engine running (choke wide open) adjust idle
speed screw to specified idle speed, (automatic

transmission in drive, synchronized transmission in

neutral).

5. Adjust idle mixture screw to obtain highest steady

vacuum at specified idle speed.

NOTE:
On air conditioned vehicles, turn air

conditioning to the "on" position and hold the

hot idle compensator valve closed while adjust-

ing idle speed and idle mixture screws.

NOTE:
On Rochester BV carburetors the idle

mixture screw should be turned out 1/4 turn

from the "lean roll" position. The definition

of "lean roll" point is a 20 to 30 rpm drop

in engine speed obtained by leaning the idle

mixture.

6. Repeat Steps 4 and5 as needed for final adjustment.

NOTE:
If necessary, final adjustment of the \

carburetor may be made with the air cleaner

installed.

7. Turn engine off, remove gauges and install air

clearer.

CHEVROLET CHASSIS SERVICE MANUAL

ENGINE FUEL 6M-5

3.
Disconnect choke rod or choke cable.

4.
Disconnect accelerator linkage.

5.
If equipped with Automatic transmission, discon-

nect TV linkage.

6. Remove carburetor attaching nuts and/or bolts and

remove carburetor.

Test Before Installation -

It is good shop practice to fill the carburetor bowl

before installing the carburetor. This reduces the strain

on the starting motor and battery and reduces the pos-

sibility of backfiring while attempting to start the engine.

A fuel pump clamped to the bench, a small supply of fuel

and the necessary fittings enable the carburetor to be

filled1 and the operation of the float and'intake needle and

seat to be checked. Operate the throttle several times

and check the discharge from the pump jets before in-

stalling the carburetor.

Installation

1.
Be certain throttle body and intake manifold sealing

surfaces are clean.

2.
Install new carburetor to manifold flange gasket (if

required).

3.
Install carburetor over manifold studs.

4.
Start vacuum and fuel lines at carburetor.

5.
Install attaching nuts and/or bolts and tighten

securely.

6. Tighten fuel and vacuum lines.

7.
Connect and adjust accelerator and TV linkage.

8. Connect choke tube or choke rod.

9. Adjust idle speed and mixture, then install air

cleaner. #

Fuel Filter Maintenance

1.
Disconnect fuel line connection at inlet fuel filter

nut.

2.
Remove inlet fuel filter nut from carburetor with a

1"
box wrench or socket.

3.
Remove filter element and spring (fig. 4c).
Fig. 5C-Choke Coil-L6 Engine

4.

Fig. 4C-Fuel Filter
Check element for restriction by blowing on cone

end, element should allow air to pass freely.

5.
Clean element by washing in solvent and blowing out.

Blow in opposite direction of fuel flow.

NOTE: Element should be replaced if plugged

or if flooding ocpurs. A plugged filter will

result in a loss of engine power or rough (pul-

sating) engine feel, especially at high engine

speeds.

6. Install element spring, then install element in car-

buretor so small section of cone faces out.

7.
Install new gasket on inlet fitting nut then install

nut in carburetor and tighten securely.

8. Install fuel line and tighten connector.

Choke Coil Replacement

L6 Engines (Fig. 5c)

1.
Remove air cleaner then disconnect choke rod upper

clip.

2.
Remove bolts attaching choke coil to manifold, then

remove choke coil and choke rod as an assembly.

3.
Disconnect choke rod from choke coil.

4.
Connect choke rod to new choke coil and install as-

sembly on manifold.

5.
Install bolts and tighten securely.

6. Adjust and connect choke rod as outlined.

7.
Start and warm-up the engine then check operation

of choke and install air cleaner.

V8 Engines (Fig. 6c)

1.
Remove air cleaner then disconnect choke rod upper

clip.

2.
Remove choke coil as follows:

WITH ROCHESTER 2GV CARBURETOR

• Remove the choke coil shield by prying with a

screw driver in the cut out provided then re-

move the choke rod.
