This simple vapor carburetor will run any engine when you have carburetor problems and can't buy a new one.
I have built these for years and it's so simple a cave mane can do it.
Enjoy this video. :o

Thank's Tommey
Very interesting stuff, i will give it a go.
As my language is not english, i have not well understood what is your mixing and what can be used in the bubbler?
Can you please explain more.
Thank's
Laurent
HI,
You can mix just about anything in the vapor carb, I have lots of dirty oil mixed with gasoline.
It burns so clean that no smoke was seen.
Remember, you are only going to vapor gasoline or other flammable liquids.
If you add water to your gasoline mixed you will burn up the gasoline, and water will be left over.
Tom
Thank's Tom
I will prepare a test jig for testing this,
Too much puzzling this experiment
Many thank's for sharing

This is a test run on a old 25hp Honda engine using my simple vapor carburator.

Tommey,
I have or often buy a bunch of tools with ICE engines. This carb sounds like something you can use when you look at an old car or rototiller/weedwacker with a carb that has been gunked up for 25 years. Would this work as a replacement carb for a while? Do you think it can be modified to run a car 4-6-8 cyl? I would love to know if what I am buying problems are before I take it home. Seems very simple, I just need to make it mobile. I assume it needs a tight vacuum. Again thanks.
Hi Rigel4,
Yes this works even for the big engines, I ran my 4cylinder off a 1L jar with 1/2 ball valves and tubes.
You will have to use some of the exhaust heat to keep is from freezing up, it will get super cold due to vacuum.
Tom..
You don't see any need for a check valve in the event of back-fire?

I ran a pontiac sunbird off of a cookie jar similar to your setup. The fuel in the jar gets cold and separates the "light parts of the fuel, which are burned, from the heavier parts, which are left in the jar. If one continues to run the engine, the fuel in the jar becomes only heavy parts and will not run the engine. (even if warmed up again, because the light, volatile parts of the fuel have burned). Gas vaporizes between 70 degrees or lower, and the heavy parts vaporize at up to 400 degrees. Can be dangerous to heat gas to that temp., so be very careful. I found it interesting, but not practical to use because of the separation issue of the fuel and heat requirements.

Hi Liberty,
I agree that adding too much heat would not be good.
I will show in the next few days how I use the heat to crack cooking oil into a vapor to run a gasoline engine.
Thanks for the input.
Tom.

That would be interesting to see a gas engine run on cooking oil. I have seen a diesel engine start on diesel and warm up cooking oil, then switch to the cooking oil, once it is liquid, and it runs. Just want to make sure you switch back to diesel before stopping the engine, so cooking oil does not solidify in the engine, but rather only diesel is in the engine so it will start again.
