Carburetor Weber 36 TLP
4. This carburetor is installed on low tuned versions of the XU5 engine and is a single barrel downdraft carburetor with manual choke. The vacuum unloader provides a slight opening of the choke after the engine starts.
5. Idle speed is adjusted as described in section 7. The location of the quantity and quality screws is shown in B / fig. 12.17 and 12.18. The quantity screw controls the volume of the mixture passing through the bypass channel of the idle system.
6. The carburetor is rebuilt according to the same principle as indicated in section 11. Other adjustments are described later in this chapter.
Carburetor Solex 32-35 TACIC
7. This carburetor is fitted to XR5S engines and is a dual chamber downdraft carburetor with automatic choke. The chambers work in series, so that at a small or medium throttle opening there is the effect of a small single carburetor, and at a large throttle opening, two carburetors. A special locking device prevents the second chamber from starting when the engine is cold.
8. Because this carburetor uses the same idle bypass system as the Solex single barrel carburetor, the idle adjustment procedure remains the same as described in section 7. Other types of adjustments are listed later in this chapter.
