Description
Overview:
This slow running tube is a genuine Zenith component for the 13TC carburettor used on classic JAP engines, including JAP 2A, as well as selected Suffolk machines. It forms part of the idle fuel circuit, metering fuel at low engine speed to stabilise tickover and improve pick-up from idle. The tube is typically machined from brass for durability and corrosion resistance in petrol fuel systems. Supplied as unused old stock, it may show light tarnishing from age, which does not affect performance. Ideal for maintaining originality and restoring reliable running on vintage machinery, this part provides a direct fit to the Zenith 13TC carburettor without modification and helps retain authentic specification on period engines.
