Here we have a Horizontal Pump Jet Conversion Kit for Solex DDH carburetors.

Originally, the DDH carburetors come with vertically squirting pump jets which is not ideal as the air flow is of course horizontal.

This set, which suffices for 1 carburetor, allows you to modify your carb to horizontally squirting jets.

Each set consists of the following parts:

• 2 pump jets - size of your choice (see below for available sizes)
• 2 red gaskets
• 2 jet holders
• 2 o-rings for the holders

Shown below are images which allow you to quickly identify if your carburetor is currently equipped with horizontal or vertical pump jets:

The modification is very easy to perform as it is basically encompasses just swapping the jets and securing them with a holder (supplied).

The jets themselves are available in the following sizes:

• 30
• 35
• 40
• 45
• 50
• 55
• 60
• 65
• 70

As visible in the photo, the size, or calibration if you want to call it that, is engraved into the jet itself.
That way, you can always determine "what it was when it was produced".

In order to purchase the correct size for your carburettor, you need to make a choice through the drop down menu just above the "Add to cart" button.

Required quantity per carburetor: 1 set
