WEBER 2V TLD Carburetor — Design Description (Scorpio 1)

The Weber 2V TLD carburetor is identical to the carburetor Weber 2V, is installed on DOHC engines, but has the following differences from the Weber 2V carburetor:

• the secondary throttle valve is vacuum controlled;
• fuel shut-off valve installed;
• an air damper with electrically heated automatic starter and vacuum and mechanical "pull down" opening systems is installed;
• the throttle damper dampens the abrupt closing of the throttle and reduces exhaust toxicity. The tappet is controlled by vacuum from the intake manifold. When the throttle opens, the vacuum actuates the tappet, which opens the throttle further than at idle. When the throttle closes, the damper slows the throttle closing. This reduces the amount of burnt fuel mixture entering the engine when the throttle closes, thus reducing CO;
• there is no stepper motor, and the idle speed is set manually using an adjusting screw.
