How to set the injector of a Lister CS 3/1

Well guys and gals, I have finally put my thinking cap on and solved my Lister CS 3/1 engine problem out. It is now running like a dream, I have uploaded 2 video's to google video, the links will be posted once google have okay'd them for me..........

Here is how I logically re tuned my injector nozzle on my engine to get it to fire correctly :-)

1. Take out injector from head and clean with clean dino 'Diesel'
2. Inspect nozzle and injector hole, clean with copper strand of wire to make sure it is unclogged.
3. Make sure the nozzle glides freely within the injector housing.
4. Re-assemble injector and make sure you refit the copper abspestos washer on the nozzle tip.
5. Unscrew tension screw and locknut on top of injector fully and then blead fuel system of air (See manual for details) 6. Replace injector and tighten back onto head.
7. Turn over engine and make sure the injector is air tight i.e. No hissing from injector body when under compression.
8. Set compression changeover to high, fully wound in.
9. Set fuel govner to full.
10. Try turning engine to speed and start, you will most probably get nothing but fear not..........
11. Now turn tension screw 1/4 turn clockwise (Tighten) and repeat step 10...........
12. If the engine does not fire, go to step 10 and keep going until you get the engine to fire.
13. Once you get ignition advance tension by 1/8 (Clockwise) until it begins to die, you can then retard by 1/8 steps until optimum injector setting is found!

NOTE: I would strongly advise anyone who has a running engine NOT to touch the injector settings as this has taken me over 2 months to rectify, use this as a last resort.

14. Take a digital picture of your injector tension screw from above and from the side once you are running so you can count the threads when or if you need to clean / strip your injector.

15. Stand back and smile from ear to ear!!!
