                                     summary

      Redline, Inc., a distributor of Italian made Weber carburetors, has

applied for exemption from the prohibitions of Vehicle Code Section 27156 for

the Redline Carburetor Exchange Kit No. K8904 using one (1) Weber model 32/36

DGEV33B1 carburetor.

      The Redline Carburetor Exchange Kit replaces the original equipment S.U.

HIF6, HS or HD l—barrel carburetors or the original equipment Zenith—Stromberg

175—CD—2 1—barrel carburetors on 1968—72 model—year Volvo vehicles.     The

original equipment air cleaner is not retained in the Redline Kit

installation.    The Redline Carburetor Exchange Kit utilizes an open type air

cleaner which the staff has determined does not increase evaporative

emissions.   An anti—dieseling solenoid is installed in the idle circuit of the

Weber carburetor to prevent the engine from running on after the engine has

been shut off.

      Comparative exhaust emission tests demonstrate that the aftermarket

Redline Carburetor Exchange Kit No. K8904 using one Weber model 32/36 DG@EV33B1

carburetor does not adversely affect emissions.   Based on the results of the

tests and the evaluation of the Redline Carburetor Exchange Kit, the staff

recommends that the exemption be granted as requested for the 1968—72

model—year Volvo vehicles equipped with B18, B20 or B208 engines.

EVALUATION OF THE REDLINE CARBURETOR EXCHANGE KIT NO. K8904 USING MODEL 32/36
DGEV33B1 WEBER CARBURETOR FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CoDE
SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13 OF THE CALIFORNIA
ADMINISTRATIVE CODE


I.     INTRODUCTION

       Redline, Inc. of Torrance, California, a subsidiary of Imported Parts

and Accessories Corporation (IMPAC), is a distributor of Italian made Weber

carburetors.   The company has applied for exemption from the prohibitions of

Vehicle Code Section 27156 for a Carburetor Exchange Kit designated as Redline

Kit No. K8904 utilizing one (1) Weber model 32/36 DGEV33B1 carburetor.     The

Carburetor Exchange Kit is designed to replace the two (2) original equipment

manufacturer (OEM) constant velocity carburetors as found on 1968—1972

model—year Yolvo vehicles equipped with B18, B20 or B20B engines.

       This report describes the evaluation of the Redline Carburetor Exchange

Kit and the findings.

II.    CONCLUSION
       Comparative exhaust emission data and other information submitted by the

applicant demonstrated that the Redline kit using one {1) Weber model 32/36

DGEV33B1 carburetor meets the Air Resources Board (ARB) requirements for

exemption from the prohibitions of Vehicle Code Section 27156.

III.   RECOMMENDATION

       Based on the submitted comparative data of the Redline Carburetor

Exchange Kit, the staff recommends that Redline, Inc. be granted exemption

from the prohibitions of Vehicle Code Section 27156 for the Redline Carburetor

Exchange Kit No. K8904 using one (1) model 32/36 DGEV33B1 Weber carburetor for

1968—72 model—year Volvo vehicles equipped with B18, B20 or B208B engines.


IV.   DEVICE DESCRIPTION

      The Redline Carburetor Exchange Kit No. K8904 uses one (1) Weber model

32/36 DGEV33B1 carburetor to replace the two (2) OEM constant velocity

carburetors.   The OEM carburetors are of the single barrel sidedraft design;

the venturi area is automatically changed according to engine air intake.        The

amount of fuel passing through the main jet is governed by a tapered needle

which moves proportional to the engine air intake.     A choke valve and

auxiliary nozzle are used for cold starting.     Main components of the

carburetor consist of:     a float chamber, suction chamber, suction piston,

piston damper, metering needle and jet, throttle valve body, choke valve and

auxitiary nozzle (See Appendix A).

      The Weber 32/36 DGEV33B1 carburetor is a progressive two—barrel down—

draft design (see Appendix A).    The Weber carburetor uses a mechanically—
operated secondary which starts to open after the primary throttle opens

approximately 68 percent.    A diaphragm type accelerator pump is actuated by

throttle movement and injects fuel into the primary barrel.     The Weber is

fitted with an anti—dieseling valve in the idle circuit which shuts off the

fuel supply to the idle circuit whenever the ignition is switched off.     The

addition of this anti—dieseling valve upgrades the emission control of the

Volvo vehicles since the OEM carburetors were not equipped with such a

device.   The calibration of the Weber carburetor is included in Appendix B.

      The DGEY model Weber carburetor is fitted with an electric choke which

is more precise and consistent than the manual choke used on the OEM

carburetors.

      Included in the Redline kit is the Weber carburetor, intake manifold,

air cleaner, throttle linkage, and all necessary hoses, clamps and fasteners

needed to install the Weber carburetor correctly.


¥.       EVALUATION PROGRAM

         The applicant performed comparative CVS—75 exhaust emission tests at

Import Certification Laboratories in Anaheim, California.               A 1970 Volvo

equipped with a 820 engine and 4—speed manual transmission was used.                The

baseline test was performed with the OEM carburetors.               A representative

production Redline Kit No. K8904 was used for the comparative testing.                 The

results of those tests are in Table 1.


                                            Table 1

        A 1970 model—year vehicle was used as the test vehicle.             It would be

expected that vehicles of previous model—years would have the same degree of

performance/emissions impact as the vehicle tested when using the same Redline

Kit.

         The applicant performed comparative evaporative emissions testing to

demonstrate that the open—element air cleaner does not increase the

evaporative emissions from the Volvo vehicles.           The same 1970 Volvo was tested

using the Sealed Housing Evaporative Determination (SHED) procedures.               The

results of these tests are shown in Table 2.

VI.   DISCUSSION

      The applicant‘s submitted comparative emissions test data are

acceptable.   The comparative data show that the HC and NOx emissions are below

the baseline values.   The change in carbon monoxide emissions is within the

limits of test variability.   The evaporative emissions decreased by more than

50%, as compared to the baseline, with the Weber carbuetor and open type air

cleaner installed.

      The kit provides the necessary components and installation instructions

to allow the average mechanic to connect the OEM emission controls to the new

intake manifold and carburetor so that they function properly.

      This kit offers an economical alternative to the repair or replacement

of the OEM constant velocity carburetors.   Since the Volvo vehicles are

equipped with dual carburetors which require synchronization {an

adjustment/balancing procedure which requires special tools and a qualified

mechanic) on a regular basis while the single Weber does not, the vehicles

will stay in tune longer with the Weber carburetor.

    All tune—up specifications for the Weber Carburetor remain the same as those specified by the Factory,
    for the original unit. Emissions tune—up should be carried out by a suitably qualified Dealer or indepen—
    dent garage, using infrared gas analyzing equipment.

    NOTE: Late model vehicles fitted with Emission Contro! Systems have many vacuum lines and electri—
    cal connections in their fuel systems. It is essential when dismantling, that disconnected lines be
    identified with a corresponding number tag or label system. To establish function, locate and identify
    the source of each line.


     1. Remove the vehicle‘s gas cap.                                5. Disconnect the ignition advance vacuum line,
                                                                        from the bottom of the front carburetor.
     2. Disconnect the battery.                                          Disconnect the valve cover breather hose

      . CAUTION: Engine should be cold before                            manifold. Remove the vapor cannister hose
        performing this step. Drain the engine cool—                     from the base of the front carburetor. Dis—
