Hi Phil,
We were on a road trip several years ago and had the Centa unit become loose on the crank. It evidenced itself as a barely audible jingling sound while running and making a horrible jangling noise at idle. We finished the trip towing the Morgan to the LA dealer (some 600 miles).
Our Morgan had a Centa up grade while the engine was out for a frame swap. The mechanic in LA said the issue was the the nut which held the coupler to the crank shaft had been improperly torqued. He showed me a large crush washer that was not properly “crushed”. It was a very expensive fix and made question the sanity of extended road trips in the Morgan. I can handle cam belts, fuel pumps, regulators and the occasional broken valve spring but this left us dead in the water, so to speak.
