Hi, I am having trouble starting my 2CV, it will not fire at all until I drop a minute amount of fuel down the carb, it then fires immediately and will continue to start first hit all day. the next morning, I have to go through the same ritual, seems like a possible fault is the fuel must be draining from the carburetor and by the time it pumps back up to the float bowl, the battery is tired and it will not start. Is this a common problem?:confused:
Rob6 Jun 2012 at 1:22 pm #781AnonymousInactiveits not a common problem, try fitting a new fuel pump, or it could be the coil being damp, try changing the coil for a dry spare just before starting
another thing to try is a little aerostart before starting
6 Jun 2012 at 10:56 pm #782petitepoupeeParticipantI’m not suggesting this is Rob’s problem, but I was having starting trouble recently. Thought it was fuel at first but priming did no good. Then pulled a plug (looked good) and checked to see if there was spark: there was. What the hell, I fitted new plugs anyway and hey presto – alles gut! I can’t figure out why that remedied it, but who cares anyway.
BTW Dolly has the 123 ignition kit fitted.7 Jun 2012 at 2:12 am #783AnonymousInactiveThanks for the advise, it has a new fuel pump and new coil,if I put a little bit of fuel in the base of the aircleaner it will start immediately, from then on it fires on the key for the rest of the day. park it overnight and the problem is there again for the first start of the day. It is just the inconvenience of taking the aircleaner off and dripping a little fuel onto the base. Maybe a new battery could help, give it a bit of spark as the battery tends to wind down quickly if I try to start it without the fuel tickle. It still has a French battery, no idea how old.

12 Jun 2012 at 4:10 am #787AnonymousInactiveHi,
thanks for the advice, it is only 6volt so it does not have any grunt to begin with, I will have the battery tested, will put it on a battery load tester and see what happens
Rob18 Jul 2012 at 9:28 pm #788AnonymousInactivethe back draining of carburetter fuel indeed its a common fault of 2cv,s, including mine
when at rest the fuel in the carburetter bowl back-drains back down the fuel line gradually,
it takes a minuit or two of engine cranking to re-fill the bowl,
theres a non-return fitment that can be fitted into the rubber fuel pipe to eliminate this problem18 Jul 2012 at 9:33 pm #789AnonymousInactive18 Jul 2012 at 10:34 pm #790AnonymousInactiveThanks for the advice, a trip to Repco is in order, I will fit it and let you know the result
