WARNING:
In all cases where the fuel line has been cut, it is essential that it be clean to ensure that no metal
particles enter the fuel bowl after the new carburetor installation. Remove the fuel line at the
pump and blow the line clean with compressed air. DO NOT use the procedure where the coil
wire is disconnected, the engine cranked for a few revolutions, and the fuel collected in a
container. This procedure is unsafe because sparking can occur either at the coil or at the
distributor end of the coil wire and ignite any fuel spilled in the engine compartment.
MAINTENANCE WARNING: Fuel system components, including fuel lines and the carburetor, should be
inspected periodically to assure no fuel leakage a
nd to ensure the soundness of the hoses. Today’s clean
emissions engines provide higher temperatures in the engine compartment. These high temperatures promote
faster aging of non-metallic materials.
Hoses that exhibit surface cracks, when bent to 180°, should be replaced. The presence of liquid fuel demands
tightening of fittings, hose replacement, and re-torquing of the fuel system component flange nuts.
Connecting the Throttle Linkage
NOTE: Before connecting the linkage, operate the throttle lever to assure the correct travel (no sticking or
binding), by opening to wide-open throttle and back to closed throttle several times. Correct any
sticking or binding conditions before proceeding.
NOTE: If installing on a GM vehicle where the throttle cable needs to utilize the large hole in the top of the
throttle lever, a part # 1952 GM throttle linkage cable attachment bracket will be needed.
With the pedal held firmly against a stop or the floorboard, pull the carburetor to its wide open position. Adjust the linkage
rod or cable to the proper length, and then attach it to the baseplate linkage. Remember, the pedal should make contact
with a positive stop, just as the carburetor gets to wide open throttle. With the linkage rod or cable attached to the
baseplate, make sure the carburetor can return to its curb idle position. Install your return spring(s) to the bottom of the
throttle lever as shown in Figure 2, and check again for smooth operation to wide open throttle, and then closed again
.

Connecting the Transmission Linkage
GM TH350, 200R4 /700R4
Attach the transmission kickdown stud (supplied) into the proper hole location on the throttle lever as seen in (Fig. 2).
Attach the TV cable to the stud and adjust per transmission manu
facturer’s specifications, using Chilton®, Motor®, or
other repair manual designed for your specific transmission.
WARNING:
If you are unfamiliar with overdrive transmission TV cable adjustments, consult a qualified
transmission expert. Failure to properly adjust the TV cable on overdrive transmissions can lead
to poor shifting and / or transmission failure. Demon Carburetion assumes no responsibility for
transmission damage or failure caused by improperly adjusted TV cables.
