I'm continuing to enjoy the joys of owning an older vehicle. I have known for a while that the carb is getting worn and also the distributor was past it's best. I have gradually saved up and got a refurbed carb and and new distributor. I eventually got these fitted and the van runs a lot better - smoother acceleration, not as jerky etc.
But it's running too rich - and no matter what I do to adjust the carb I can't seem to cure it. I'm beginning to thing that there is also another underliying problem as it only seems too rich on cylinder 3 & 4, judging by the spark plugs. So now I am frequenting the VW forums asking further questions about tuning. Everyone has an opinion on how to tune the carb, but no-one seems to give any ideas as to why only 2 cylinder are affected.
It's getting to the point where I may have to do the unthinkable and take it to a garage!
