- Data Sheet
DetailsPilot jets for 19 and 21mm carburetor from Dellorto (type PHBG). In some cases, the pilot jets may be too small or too big, which you can see from the scooter's throttle response. If you start the engine but only manage to ride about 10m at walking speed, then the pilot jet is too small. If the engine splutters up to about 1/4 of the throttle, the pilot jet is too big.
