Once you go leaner than 18:1 and HC starts going up.
I shoot for 17-18 to 1 on my carbs idle.

Closest thing I have seen to the miracle carburetor is the original Honda CRX 1.3 which got 73 MPG at 55 MPH when tested by one car magazine.

Some people are following here. This is why Indian and Chinese companies are working on ceramic engine development. In an ICE, you can't control the 'burn' of high pressurized (fuel injected) fuel at extremely high AFR's. You can however control it at lower pressures, i.e. carbureted, and those AFR's could be reached easier with a vapor that hits its autoignition temperature without spark being applied. (the problem is how do you bridge the gap from rolling out of spark, so far the only guy we know that did this is Yunick, would be a nice project later in life). With the added 'efficiency' benefit not only of the extreme AFR but of the fact that no high energy ignition, or ignition at all, is needed after the engine is at operating temperature. In theory an alternator working full time/automatically would not be needed as well.

Smokey's design failed because of personal outlook/politics, and the fact that it was extremely impractical for the average consumer, who wants to hop in their car and start it up and go for a drive, not to wait for operating temperatures or worry about extreme engine heat.

How odd, the average consumer here runs it for half an hour before climbing in.

Weird isn't it, that consumers will idle while reading a book, drinking a smoothie, or putting on makeup but don't want to wait a few minutes to double their gas mileage on something like this design. Instant gratification is what Amurica's all about

Hardy har har!!

I actually tried acetone in the Civic I used to own. I fell for the unicorn trap. At least it only cost me $5. Now I have something to clean paint brushes with.

If you run an engine lean under load you will burn valves.
Even the lean burn civic only ran lean at light load.
Replacing exhaust valves every 10k miles isn't very economical.

I am surprised no one mentioned this , In the mid 80's GM (not sure on other manufactures) used a electric heater grid under carb to help with vaporization of the fuel and probably emission too .
This things would not last long an burn out or even melt the grid after a while (few yrs) .

....I, too, tried acetone -- once -- with disasterous results. It "ate" all the gaskets in the carburetor, which then leaked like the proverbial sieve! Co$t me much, much more than $5 to repair the damage, though.
