                                    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. K8055 using one (1) Weber model 32/36

DGEV33B1 carburetor.

      The Redline Carburetor Exchange Kit replaces the original equipment dual

S.U. HIF 1—Barrel carburetors on 1968—74 model—year MGB 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.   A delay valve is added to the gulp valive vacuum control line so

that the gulp valve functions pfoperly with the Weber carburetor.   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. K8055 using 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—74

model—year MGB vehicles equipped with 1.8L "B" series engines.

EVALUATION OF THE REDLINE CARBURETOR EXCHANGE KIT NO. K8055 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. K8055 utilizing one (1) Weber model 32/36 DGEV33B1 carburetor.     The

Carburetor Exchange Kit is designed to replace the original equipment

manufacturer (OEM) dual S.U. HIF T—Barrel carburetors as found on 1968—1974

model—year MGB vehicles equipped with 1.81 "B" series engines.

       This report describes the evaluation of the Redline Carburetor Exchange

Kit and the findings.

I1.    CONCLUSIONS
       Comparative exhaust emission data and other information submitted by the

applicant demonstrated that the Redline kit using one (1) Weber mode! 32/36

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

exemption from the prohibitions of Vehicle Code Section 27156.

III.   RECOMMENDATIONS

       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. K8055 using one (1) model 32/36 DGEY33B1 Weber carburetor for

1968—74 model—year vehicles equipped with 1.8L "B" series engines.


IV.   DEVICE DESCRIPTION

      The RedTine Carburetor Exchange Kit No. K8055 uses one (1) Weber model

32/36 DGEV33B1 carburetor to replace the OEM dual S.U. HIF 1—Barre]

carburetors.   The S.U. HIF 1—Barrel is a single barrel sidedraft carburetor;

its 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

auxiliary 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 diaphram 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 MGB

vehicles since the OEM carburetors were not equipped with such a device.

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

is more accurate 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.
