I discovered the same problem when I experimented with a gallon-size pickle jar bubbler-type evaporative carburetor. The lighter fraction came off first, then I was left with the heavier portion. At the time, I didn't really think about the need for increased temperature.
I need less restriction in the plumbing for something like that to work. The heat gun I tried I could set to low (250 watts), but even with the fan on high, there wasn't enough pressure. Still, something to think more about...
I put one together with the wick system instead of the bubble or heat system . It runs a gas gene great at super efficiency levels. However in my experience the wick system still leaves u with stale fuel left over like the bubble or heat method .
Interesting. Using a torch first as the gas vapor consumer, I figured I could narrow in on problems easier. So far I found that if I applied a little heat from my hot air gun, the torch would still burn until the wicking filter paper is almost complete dry. I know if I place a drop of gasoline on a cold piece of steel, (even if it was -20˚F), all of it evaporates. So I would still think it would be a matter of having enough surface area, and enough heat to keep delivering enough gas vapors to be useable. Anyway that's what I'm working at.
@@doubleMinnovations cool man 👍. Perhaps the gas I was using is different than what u are using . Bet ya my results were showing gas around here is full of water for cheapness and car wrecking ability
@@doubleMinnovations my mistake aswell the heat method doesn't leave it stale it's just a bit dangerous . So I have high hopes for your wick/heat method of vapour carb. I know bubblers are bad for making fuel stale .
I had the same experience with bubblers, though some say they got them to work. I only seen one other who tried a kind of wick vapor carburetor about a decade ago. And did pretty well on his lawn mower. Just don't know the 'untold' story.
