[QUOTE="rapcom, post: 62893, member: 191"] Michel, One of our section members had a similar, and very puzzling, problem on his Rapide, when the valve lifter worked on only one cylinder and not the other. Eventually I found that the problem was that the thread in the crankcase for the rear ET68 was very badly worn, and operation of the mechanism simply tilted the rear ET68 without moving the ET69, but still operated the other lifter. Perhaps your thread is gripping when cold, but expanding and losing the grip when hot? [/QUOTE]

Verification
The Series 'A' Rapide was known as the '********' Nightmare?
