I saw a picture of a set of HD8's on the internet that had the diaphragm mixture screw secured with a spring. Mine is secured with a nut. Not that one does this more than once, but tightening the nut is a royal PITA. Was the nut design a replacement for the spring because they 'walked'? |

Crow foot spanner is what you need. bend a flat spanner at say 70 degrees angle. |

Hi Ross, My Jag MK 2 SUs have a spring. My roller has nuts as do yours. I always asked myself the same question. My Jag is a 1965, and the Roller is 1974. Both work well, but does this mean that the nut was a natural progression from the spring? I don't know, but I leave well alone! What I have in the Rolls, is a 1/4 inch ring spanner with a 6" length of doubled up thick binding wire strapped to it with some tape, giving the spanner a "bendable" extension which makes it easy to engage the spanner on the nut. |

Robert and Patrick, Both god ideas on getting the nut tightened, but if the spring works, I might just find and fit some springs. The engine runs so smooth I just don't see a problem with the idea. |

Lots "later" cars had locknut on adjusting screw to prevent owners "fiddling" with adjustment as early form of emission control, nothing to do with adjustment " walking" during service. It was the start of the world as we now know it-tamperproof!! |

This adjustment is as said once set lasts for ages so I wouldn't put springs. However if you wish buy the springs from Burlin Services who own SU. Not expensive. |

I was working on the car a couple days ago and made one of these. Works good.
