Guys thanks for all the useful comments. The distributor is a DJ4-7 manual advance retard (the mechanism long since discarded by previous owners). Ignition was set at 1 and 1/4 inches on the flywheel before BTDC. Piston works perfectly in the SU which is mounted at an angle to the manifold. The vacuum port is blanked off. Latest development is that she starts but with throttle fully closed runs at fast idle. This can be adjusted a bit by retarding the ignition.
When I originally dismantled the carb there were two fibre washers under the 3/8th nut that secures the jet assembly. I think this was to reduce the level of the jet assy. Even though it runs at fast idle it is very unresponsive to the throttle. i.e. if you open the throttle the revs pick up very slowly. I am beginning to think about the condenser breaking down under load. Curious thing is that the engine ran pretty well before the strip down so it's something I have or have not done. Thanks again Martin
