S-jet inlet valve
The Genuine Stromberg twin-ball S-jet is the 'next generation' needle
and seat. It's designed to eject dirt particles and improve high speed
running and, unlike many a so-called viton-tipped needle valve, it won't
stick or melt in today's corrosive new gas formulas. Comes with a new
fibre washer. Fits Stromberg 97, 48, 81 and 40.
