The traditional multi circuit carburetor is not required for vapor fuel, but is less expensive than producing new twin circuit carburetors designed specifically for vapor fuel. All carburetor air vents should be plugged so engine vacuum signals draw only from unvented carburetor fuel bowl, which is connected to fuel bubbler in tank or racing fuel cell. The fuel float and needle valve assembly is removed. Any accelerator pump is removed and enrichment hole is plugged. In carburetors that use vacuum power valves, such can be used to fine tune vapor flow according to vacuum signals. The idle circuit must retain adjustment from barely open to wide open.

Rod and jet enrichment systems such as used on Carter and Rochester carburetors can also be used to fine tune vapor mixtures. Go as lean as you can without engine stumbling under load on power circuit and richen slightly for best throttle response. If max power metering is sufficient with selected main jets, which flow much more vapor than liquid, we can regulate maximum fuel supply by means of an adjustable valve in supply line. Start fast burn engine with idle mixture screw open wide and quickly close it after engine starts. Back adjustment screw off one turn after you stall engine for lack of idle fuel. Too much idle fuel could melt engine parts as easily as too much fuel in power circuit. If we never meter more fuel than can burn in half a power stroke, we avoid meltdown while maximizing power and fuel economy, minimizing exhaust emissions. With fast burn, we want to retard initial spark timing to between sixty and eighty degrees after top dead center. On a V-8 we can move each wire in distributor cap forward one position on cap in direction of rotor rotation. This will retard timing 90 degrees from standard initial timing. A timing light on number 8 cylinder will allow you to set initial timing with stock timing marks. Setting number 8 cylinder for ten degrees advance would have number one cylinder firing at 80 degrees after top dead center. 20 degrees advance would have number one firing at 70 degrees ATDC, etc. An aftermarket timing tape, when available, is another way to accurately set spark timing. Otherwise, one can remove crankshaft dampener or pulley with timing marks, measure circumference, divide by 4 and mark at 90 degrees ATDC, 85, 80, 75, 70, 65, and 60 degrees. Marking all way back to 30 degrees ATDC is a good idea. This is most advance likely practical for max fast burn power and allows one to check for total mechanical or electronic spark advance. Optimum timing for best performance and economy, like fuel mixture, must be worked out by road testing converted vehicle.

Fully vaporized fuel is likely to be combustible over a wide range of air/fuel ratios. As a safety precaution it makes sense to install a PCV valve or something similar. Should a timing chain let go or an intake valve bend, we don’t want fire in intake manifold to find its way back to our bubbler and explode it. Better that a fuel supply line disconnect or rupture under hood from combustion back pressure.

The bubbler where our vapor is made by engine vacuum, is a modified fuel tank or racing fuel cell. Our tank/cell must be vented to atmosphere. We want our air pick up filtered with something like a lawnmower air filter and mounted higher in or outside vehicle, than outside of fuel filler tube, which is most convenient place to tap our tank/cell for a very rich vapor.

On typical fuel tank, our air vent can be easily installed where original fuel supply line attached. We want another PCV valve near our air supply filter to seal tank from atmosphere when vehicle is not running and tank/cell is pressurized by atmospheric heat. Gas expansion in our tank now moves fuel through carburetor into intake system, where it allows instant starts, as with fuel injection.

I was touting importance of Flores Island and sea travel technology for years before recent discovery of Hobbit-like creature there. Some researchers say it is a cross between a chimp and a hominid. That would dovetail with also currently-being-researched Bonobos who are a cross between a chimp and a gorilla. The Portuguese baby that is half Neanderthal is proof of cross-breeding despite fact that these attunements are not traceable through DNA analysis as I see it. The following excerpt from an article in 2004 does not mention that researchers of human lice are now going on to check pubic lice in order to prove cross mating occurred. There will be debate no matter what they find but I think it speaks to much of sex magic in Tantra and Dragon or serpent lore including what Sir Laurence Gardner and Rosicrucians have written about.

“But it turns out that DNA analysis shows there are two distinct sub-species of head lice in humans. All over world, except in western North America, they are same. But there is a population of lice along Pacific coast of North America which have been evolving separately from rest of world for about 1.8m years. The only way to make sense of this is to assume that their separate development took place on Homo erectus, who also split off from our hominid ancestors about that time ago.
