Special Notes
 
All Spaco SI carburettors come with the longer slow running fuel mixture adjuster screw used for electric start Vespa PX models. This cannot be swapped for the Dellorto slow running fuel mixture adjuster screw as it has a M5 x 0.5mm thread and the Dellorto is M5 x 0.75mm. Due to the longer fuel mixture screw the later type carburettor securing bolts and air box fuel mixture screw grommet should be used.
