    Default 505 starting problems

    Until a few months ago I was able to turn over the XN engine on the fourth key turn and everything was okay. That is, a fast warm up period and smooth idling.

    A few weeks ago it became necessary to prime the carby for each cold start by lifting the air intake and delivering a small amount of fuel to each throat.
    Apart from the inconvenience of this start up procedure all was okay.
    Starting anytime later in the day was no problem, turning over first go.

    Now it is a bit difficult to keep the engine running from a cold start
    and the engine behaves like "bronco billy" and the bonnet almost leaves its
    hinges.
    Within five minutes it is then idling smoothly and after driving off there are no
    problems.
    However starting later on the same day can now sometimes require a re-priming of the carby.

    Would appreciate any advice on steps to take to alleviate the above.
    The car has an auto tranny and someone in the past has converted
    the auto choke to manual on the Webber.

    I've encountered these symptoms many times. It's rarely a carby problem. It almost always turns out to be the points gap (which closes up due to the rubbing block wearing).

    Re-adjust the points, reset the timing and you'll probably notice a big difference.

    I also have a 505 with a manual choke Weber carby, but it is an '84 SR, with electronic ignition. It has been very difficult to start lately, particuarly if it hasn't been used for a few days.

    I think that the problem is caused by a leaking non-return valve in the fuel pump, because after a day or two, the fuel filter (just near the carby inlet) ends up completely empty. It takes a lot of cranking to get fuel back to the carby. Might have to get around to buying a new fuel pump to test the theory.

    stick an electric pump on it

    just turn the key and wait a couple of seconds then crank it over

    they also tend to last for a very long time and the other bonus is if you ever run the car out of fuel you need only turn the key to run the fuel up and your away again

    Andrew, have you tested your theory yet? My '83 GR has had the same problem for a long time now. I've still got the standard Solex carby on it.

    "All of its cars from the 1.1 litre 205 through the ugly duckling 309 to the 2.2 litre 505 GTi had a rightness and a righteousness about them that turned every humdrum drive into a journey. Someone, I once wrote, in the bowels of Peugeot understands handling and how a chassis should feel." - Jeremy Clarkson

    The only problem with the electric pump is that the fuel flow is constant.

    The mechanical ones vary with engine speed. I am sure that there is some way to tie the pump to engine speed but until i can figure that out it would seem that the mechanical type would use less fuel?

    Try checking rubber air hoses for leaks - use detergent.
    Good luck.

    that's what needle and seat is for on the carb to keep a constant level in the bowl

    the electric pumps are low pressure and if needed it is easy to run a return line back to tank

    As Pugrambo said, the pump's got nothing to do with the amount of fuel used (unless there's a leak). All it does is keep the float bowl full.
