This is the old style, 1-piece, F5 starter jet for the Weber DCOE carburetors.
This jet has now been replaced by a separate emulsion tube and air corrector (numbers 62 and 74 in the drawing) which are NOT interchangeable with this particular version!
Due to low demand, we keep a very limited stock of these jets but it is readily available from our warehouse in sizes:
Most other sizes are available on request but do have a lead time of around 1 week.
Required quantity per carburettor: 1
This jet is NOT listed in the drawing.
