Carburettor trouble

Post by MoggyMatilda »

So my 948cc has been running very rich & sooting up the plugs. My carb is the AUC 6070. Float valve not sticking, choke not sticking, needle fine, even when I adjust the jet right in & only open it slightly it still runs rich. Can’t figure it out.

Any ideas???

AUC6070. That number does not appear on the Burlen Fuels SU carb listing for Morris Minors. Where did you obtain the number from? There should be a tag attached to the float chamber lid which gives the carb number from which the specification of the carb can be determined.
As regards the richness - have you checked the float chamber needle for serviceability and the fuel height in the float chamber.

The jet could be worn or misaligned? Piston sticking?
