Metro 1.1 Carburettor problem

[Ian Thomas]

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.

********Car Details*********

Rover Metro (pre 100 series) 1.1 k series engine 1994
SU carburettor KIF 38 charcoal canister fitted
Catalytic converter fitted

Many thanks,

how are you adjusting it ? there are two adjusting points the main jet and
the air bypass. Is the air bypass solenoid clicking open with ignition on
and throttle pedal at rest position ?
