I honestly can't figure out why it is so difficult for people to keep Webers in tune. It was surprising to hear Pat diss them. I do realize that I may have a better handle on them than most regular folks, as we seem to understand each other.
I don't recall a plugged idle jet in about 3 years.
You need:
Clean air filters(and leave them on once synched).
Clean fuel.
Recommend a stable and precise linkage.
Jet Doctors are helpful but not required.
Also recommend Spanish or Italian Webers. There was a time that the Asian copies REALLY sucked. They aren't so bad now, but they'll never be run on MY car.
The last thing you need is a little knowledge and understanding, but I can't help you with that so much.
