Sidgreaves - MD}'s experience, then I think that we ought to lock the jet pipes on the Phantom III carburetter. The other day when I was motoring to London one of these jet pipes fell out. The result was a stream of petrol on to the sparking plugs in the 'V'. This might easily have set the car on fire. I assume that the plugs are not being properly tightened. I took the matter up with the Stromberg people, who of course assured me that such a thing had never happened before. However, it is much more serious than the 20/25 failure because there is every chance of the car catching fire, if it occurs. Even if we do not actually lock these jet pipes I think we ought to have hexagon heads on them so that they can be tightened with a box spanner. It is not possible to tighten them properly with an ordinary screwdriver, particularly in view of the fact that the threads are usually rather slack in the die-casting material used for carburetter pipes.
