Hi all,
My wife's Rover Metro has failed the MOT due to excessive CO. Any adjustment to to mixture has very little effect.
This also happened 2 years ago, when the tester advised replacing the carburettor with a secondhand item from a breakers. This worked well. The CO dropped from 10% to 1%
Well, it's happened again. Can someone tell whats wrong with these carburettors?
I have noticed that when the crankcase vent pipe is disconnected from the carburettor the CO drops and is adjustable to within the set limits. This was also the case with the first carburettor.
As I am having trouble locating a carburettor in good nick, so I need some advice.
