Adjustments – Getting the 1955 Austin-Healey 100 Running Right

The restoration workshop technicians at the Bridge Classic Cars workshop based out of our Suffolk HQ have been working on diagnosing and fixing the running issue on the 1955 Austin-Healey 100.

The car came into us to look into a running issue once the car got up to temperature or if the weather itself was hot. Our technician Jon began by looking into the various systems in the engine bay such as the fuel system and intakes. He noted that the classic Healey was idling rather quickly so he rolled back the idle speeds on the carburettors to give everything a good baseline to work from. However, the carburettors are not the throttle stops so were bought down to a safe speed achieved from the screw. He did notice that the car would ”run on” after being switched off when hot but would start up near enough straight away afterwards.

Upon inspection of the points inside the distributor, Jon discovered the car fitted with electronic ignition which helps with the diagnostic as it is one system that would not need adjustment and could be relied on as a baseline.

Along with that, Jon checked and read the spark plugs on the classic Austin-Healey. After very slightly adjusting the spark plug gapping, he installed them back into the car to move on to the timing. With the timing, Jon managed to slow down the idle speed a little more. Then, he could begin road testing the car.

After numerous tests and adjustments, Jon has got the car’s engine into a good place. Although he has noted that when coming to stop at a junction it will momentarily go towards stalling, the road performance of the classic Austin-Healey is exceptional and pulls very well through each gear. The car will continue to be road tested and adjusted to get it just right for its owner.
