Hi, sorry to hear that you still have a problem with the 7 running, I know how frustrating it can be when such a simple machine seems to defy all logic and just will not run. it will probably turn out to be something very simple in the end, while you are concentrating on the valve timing, you may be overlooking the basics, look at all the leads, is the distributor cap cracked? it is also possible for a "pattern" cap to take in moisture if it is made out of a different material, B.L.I.C. magnetos can suffer from this problem also, Is the carbon brush free and long enough to give a good contact with the rotor arm? Is the spark jumping to earth rather than across the plugs? When you time the distributor you have to turn it TOWARDS the direction of rotation of the rotor for the points to start opening. Austin seven engines don't usually have a problem earthing to the chassis, but to eliminate this fix a jumper lead to unpainted metal from chassis to engine. One that's dead easy to miss are the points stiff on the pivot pin, you can get a start with this, but as the engine try's to speed up they cannot spring back quickly enough to keep it running. hope this may help Ian
