to adjustable jet for one Zenith Stromberg CD150 carburettor
Adjustable jet conversion kit
for one Stromberg CD carburetor. Originally fitted with fixed jets in their integrated float bowl, Stromberg CD2 have very limited adjustment from above through the dashpot. This design was introduced to prevent tampering with the emissions by way of mixture adjustment.
Over the years the mechanical wear of the jet meant that the vehicle could no longer be tuned, resulting in less than perfect performance and fuel economy.
This kit is easy to install as the adjustable jet is pressed into the carburettor body with no machining required. Fine tuning for the best performance can then be done via the adjuster on the end (using a screwdriver or a ½" wrench). This kit comes complete with high quality Viton O-ring seals.
