Description:

Original Dell'Orto 'LARGE-thread' (i.e. 6mm thread size) standard type jet for Dell’Orto FHB + PHBE + PHBH + PHBL + PHBN + PHF + PHM + PHSB + PHVA + PHVB + VHSA + VHSB + VHSC + VHSH + VHST + SHB 25 type DellOrto carburettors. 

Please note that these 6mm LARGE thread jets are NOT for original, standard type OE carburettors fitted to Lambretta scooters (that use 5mm jets instead).

This is an original Italian made Dell'Orto spare part. Choice of numbers between No.50 up to No.250

How do jet sizes affect my carburation? 
The larger the number is on the jet, the more fuel it supplies to the engine ("richer"). The smaller number is on the jet, the lesser amount of fuel that will be supplied to the engine ("weaker"). For example, if you fit a performance type exhaust to a Lambretta that has a PHBH 30mm carb, then you will probably need to increase the main jet (and perhaps the tick-over idle jet) size by a few numbers to increase the amount of fuel needed for perfect running, as more power is produced. If your currently fitted main jet is a No.120, you may need to increase the number of the jet to No.125, or perhaps to No.130.
