Thanks for the basic summary.  Reminds me that I have one or two junk carbs lying around. I need to take one apart just to see how to adjust everything.

As a driver of old British cars with SU sidedraft carbs it reminds one of how important vacuum is to an engine running well.

I learned all I need to know about carburetors from author **bleep** O'Kane, it's a French word for "leave it alone".

Don't know why system inserted "bleep" maybe Mr O'Kane prefers "Richard" these days...

Good article. But who shot your carb with a dirt gun?

It is pretty crusty, isn't it? This was a Rochester I had sitting in the parts pile. It came out of a field car I scrapped off a few years ago. It is still a good core and has a lot of good fiddly bits. I just haven't gotten around to cleaning it since I haven't needed it yet.

Nice article.  A follow-on that addresses more complex carburetors with things like primary and secondary jets, idle circuits, and the importance of getting all those tiny passages perfectly clean would be appreciated.  I'd also be interested in what you consider the most complex carburetors out there.
