Emulsifier DELL'ORTO BE3 40406000 For DELL'ORTO Carburetor

The mixer tube, which is located in the middle of the jet block between the main jet and the main jet correction, is responsible for regulating the mixture in the partial load or half throttle range (1/4 and 3/4 open throttle valve). In this context, it mixes the air in the main correction jet with the gasoline from the main jet. The different mixer tubes that are fitted as standard to the Largeframe models are interchangeable. This means that it is possible to alleviate a pinking in the excessively lean partial load area by means of a richer mixer tube. The better the main jet, the main mixer tube and correction jet air suit each other, the more perfectly the engine runs. The same applies to the main correction jet at the mixer tube: the higher the indicated number, the leaner the mixer tube. This means BE1 is very rich, but BE6 is very lean.

Conclusion: Excellent DELLORTO quality. Indispensable for optimal carburetor tuning in the partial load range.

SIP - TIP: The best idea is to order a main air correction jet that matches the mixer tube at the same time. For the D/H/E carburetor, SI for example 160 with BE3, 140-160 with BE5, 190 with BE4. Play with different main jets as well.
