im sure citroen state the correct Co should be between 1.5 and 2.5, so this might be why your car takes quite a few seconds to fire up, it is running way to lean, which does usually over heat the combustion chamberTinkley wrote:I doubt there is much wrong with the carb in fact. However my 150C engine got better CO content than yours something like 0.15% and one place kept telling me the engine would blow up - it never did!. My 1.6 is similar so 0.49 is something I would consider bad for a 150C!!!!
thats odd Mr TinkleyTinkley wrote: The Haynes gives 33mm for Solex 30-30 Z2 CIT348 which should be your carb. I doubt it is out, however some tit had altered one of mine (1.6) to 40 when it should have been 33 and it failed on emissions - mainly because of this.
if the float were set at 40mm from the lid instead of 33mm ( should be from the lid gasket!!! ) the float level would be to low
