I'm after a Weber 32 DIR 109 carb for a 1990, 1.4, 340 auto.
I have a running problem with mine and I think this is the issue. One minute it runs smoothly and pulls well and then the next it's all lumpy and won't idle and at around 30mph it lurches. If I pull the choke out about half way it's fine for a while. I have checked vacuum hoses and all seem ok. I changed the top of the carb and it has got a bit better, but nothing near what it should be.
Before I changed the top of the carb the mixture screw was wound quite a way out. Once I changed the top it needed to be wound in much more and I thought I had solved the problem, but no
This evening it seemed to be over fuelling, but how would that be? I thought the mixture was set by the screw and that was it? Any help would be gratefully appreciated and if someone has a working carb then that would be great.
Cheers,
James.
