    Although you might have flushed the radiator – this is no guarantee that the radiator is working efficiently.

    If the radiator has not been recored to your knowledge in the last 10 years then is it more than likely silted up beyond reasonable repair. Get the radiator rebuilder to use an enhanced higher capacity core. The company that the club used to use is GAT radiators in Brierley Hill.

    Also check your ignition timing – if it is too far advanced then the engine will overheat. Also if the carb is sent too lean.

    However it is more than likely to be a blocked radiator. Even fully blocked radiators will run clear water.

    Also you should be using a 74 degree thermostat – available through he club.

    Hope this helps.

    Thanks for the reply have sent a email to GAT about cost

    timing my Devon has always been a bit hit and miss it has electronic ignition so no points there are no marks on the front of the engine my method has been to get the engine running and then turn the dizzy to get the best result
