Compatibility
SI identifies the Dell'Orto/Spaco carburetor family used on vintage large-frame Vespa, Vespa P/PX and Genuine Stella 150 two-stroke applications. Carburetors in this family include SI 20/15, 20/17, 20/20 and 24/24 configurations. Match your carburetor's SI main-jet design before ordering; #118 is a tuning size, not a stock-jet recommendation for every model below.

|---|---|
| Vespa 125 | VNB, VNC Super 125, VNL GT/GTR, VNX P/PX 125 |
| Vespa 150 | VBA, VBB, VBC Super 150, VLA GL150, VLB Sprint, VLX P/PX 150 |

Jetting Guidance
A larger main-jet number allows more fuel flow within this jet family. The correct size depends on your cylinder, exhaust, intake and operating conditions; vehicle model alone does not determine the jet you need. Your complete jet stack also matters, so tune the combination rather than choosing #118 simply because it fits.
