384 mpg out of a scooter

Well Ive been working on another fuelmizer project. I took a 150cc scooter and made a vapor carb? out of a mason jar.
I got the idea from a few videos I found on youtube. All the ones I saw had issue with proper fuel/air ratios. As did mine for a couple of attempts.
My first attempt got great milage a huge increase in power and rpms, it also burnt a hole thru the piston in 19 miles. So I installed a new piston a set of rings and honed the cylinder.
For my 2nd attempt I restricted the airflow using a smaller intake tube to richen the mix I made it 28.8 miles and yup another hole in another piston as well as tearing up the cylinder wall. so a new piston, jug and rings got installed.
So for my 3rd try I wised up and got a little air/fuel mixture guage that goes between the plug and jug. Restricted the air flow even more,raised the fuel level in the jar. but that was still not enough. Then I tried 87 octane fuel instead of 93 as well as a colder plug. This looked good after a 100 miles or so we took the head off and there was some damage to the piston. So I was moving in the right direction. I replaced the piston but used the rings over again.
Attempt #4 I decided to use E-85 and raise the fuel level. I retarded the ignition at this point as well. After 100 miles I took the head back off, there was no damage to the piston.
This leaves the only 2 problems 1st) that the air/fuel mixture is only right @ a certain level in the jar. only 3 oz. of safe usable fuel level out of a 16 oz. jar. 2nd) Refilling the jar every 9 miles so I don't burn a hole in the piston.
What Im looking to build is a duel cavity carb, one for the fuel to be turned to vapor and one that'll have a float, needle and seat for a constant metered flow and level of fuel. The problem comes from the need for the 2 cavities to be connected (to maintain constant level) both cavities want to vaporize. This keeps my float needle in an open position continuing to fill both cavities.

Anyone got any educated ideas?????
Thanks, Rick

I can't really understand what you're talking about from your description. How does the throttle work? Is there still a regular carb?

Oops, forgot to explain that. the thottle is simply a butterfly I installed in the intake manifold, a throttle cable is attached at one end of the lever and a spring on the other end for return pressure. the engines vacum draws the fuel in

16v4nrbrgr,

The performance as it sits now is good with no visible damage to the piston. No pre ignition either. I've retarded the timing already. The hand throttle position seams to be the same as it was before, however it wasnt a detail I paid perticular attention to.

The part Im having trouble with is the dual cavity carb body
Thanks, Rick

16v4nrbrgr,
I re installed the stock carb assembly and ran the scooter then put my homemade one back on and ran it there was a 2 sec difference between the 2 from 0-35

There are a # of different ideas/inventions bought up by oil or atoumotive companies that never make it past the prototype. think about it what oil company wants 300+mpg vehichles.
If you contact any of the auto manufactures R&D departments they will tell you they are aware of all the technology! Yet it doesnt appear in any of their product line except in miniscule amounts, selling it to you a small slice at a time so you get a new model in a few years thats a little better then the last
