EMPI 1.10 Main Jet for HPMX/IDF/IDA/DCOE Carburetors — 1.10mm metering orifice | Porsche 914 (1970-1976) (43-5301-0)

On a Weber or HPMX, the main jet is where wide-open fuel is decided, and the 1.10 sets a deliberately lean starting point. A 1.10mm brass orifice for smaller-displacement or milder builds, it leaves you room to step up if the top end reads lean.
