EMPI 32mm Main Venturi for HPMX & Weber 44 IDF — mild builds | Porsche 356/912/914 1948-1976 (43-5609-0)

A 44-series carb can overwhelm a gentle engine, drowning throttle tip-in in fuel it never asked for. This 32mm main venturi keeps a 40/44 HPMX or 44 IDF honest on milder builds, favoring a clean, well-mannered signal over raw top-end.
