Idle Jet DELL`ORTO 40
for SHB 16.10/16.12/16.16
On the SHB carburettors, the choice of the idle jet primarily affects the lower and middle rev range. If the scooter runs noisily on idling mix this can be eliminated through the selection of an appropriate idle jet. The idle jets are available in a short and a long version depending on the model of carburettor. We stock short jets in sizes 30 to 60 and long jets in sizes 40 to 60 both of which are from DELL'ORTO. In contrast to the SI carburettors the following applies in this context: The lower the grade number, the leaner the mix provided by the jet.
The size of the jets increases on the basis of one, three and five stages. Simply attach the corresponding size to part no 3360 and/or 3370.
Conclusion: Important components for carburettor tuning in the part load range!
SIP-TIP: To ensure you have all the necessary gaskets to hand when working on the carburettor, order the carburettor gasket (e.g. part no 920670 SHB 16) at the same time.
