DELLORTO 93744000 CARBURETOR VALVE LAMBRETTA 125 LI SERVETA 1962-1965

Details

"If the slide is opened a little, a negative pressure occurs which means that gasoline is sucked up through the calibrator. While the mixer tube and needle determine the amount of fuel, the throttle valve controls the amount of air that is added. The cylindrical butterfly valves of the DELL'ORTO PHB series are equipped with inserts of different sizes. The larger this gap is, the more air is added to the gasoline. The resulting mix is ​​consequently leaner than in butterfly slides with a small cutaway. We have DELLORTO throttle slides for the PHBL 30-60 carburetor as well as slides for the PHBH 30-70 carburetors. Conclusion: Together with the mixer tube and needle, necessary under all circumstances for optimal tuning in the partial load range. SIP-TIP: The spring retainer plates (PHBL item no. 95632100, PHBH item no. 93752100) can be easily lost. The best idea is to order a replacement at the same time.
