TUNING TO SUIT ENGINE. Note this stage is not always necessary

A small adjustment of the valve regulating screw may be necessary to provide an improvement.

ADJUSTMENT PROCEDURE

WITH THE ENGINE TURNED OFF!

Remove the chromed domed lock nut Slacken locknut around the adjustment screw Turn adjustment screw clockwise 1/4 turn (to enrich mixture) Insome cases a second 1/4 turn adjustment clockwise will be necessary (on 5% of valves fitted an anti-clockwise adjustment of the screw will be necessary) Tighten adjuster screw. Ensure that all tools have been removed from the working area: Start Engine. Road test the vehicle and check your improvement

Your final adjustment may NOT need a full 1/4 turn movement. It is unusal that you will need to adjust the valve more than this amount

CAUTION OVER ADJUSTMENT (CLOCKWISE) WILL RESULT IN THE FUEL PUMP & LINES OPERATING UNDER EXTREME PRESSURE

This above set up works very well, you can then check it with an anologue tyre inflation gauge pushed onto the Valve at the end of the fuel rail, and with the engine running and the vacuun pipe OFF the FSE you should have a pressure of 2.1Bar.
