If this is against the rules please excuse my ignorance.
Since alot of people have been asking about carb issues. I thought it would be good to find a tutorial of exactly what the hell is happening in there. Many people do know, but I fear others do not (myself included). So I did a little google-fu and found this. It seems to be an excellent step by step tutorial (with pretty pictures for us babys) of how a CV carb works. Hint: its most likely different then that Holly you are used to.
One thing it does not go into is the enricher (choke) circuit. I wished it did. I would love to know how it works for those of us with the nipple cap carbs ( and how to disable it, for troubleshooting purposes). Anyway, have a look, I found it very informative!
