My recently purchased 1974 Quatrelle is a beautiful timewarp car. She does however suffer from the same problem that has affected every carb-fed French car I have owned - namely, difficulty in starting when left overnight. What I think is happening is that fuel evaporates from the carb float chamber, & from the pump to carb pipe (? possibly due to weak valves in the pump). It takes a lot (sometimes 1 1/2 batteries -worth) of churning on the starter to fill the carb & persuade her to fire. Once she has started, she will start first turn for the rest of the day. My 1962 works workshop manual tells of a fuel pump with a priming lever - does anyone know if these are still available? I had thought of lagging the fuel line with heat-shielding tape. Anyone got any other ideas?
