This is the proof-of-concept of the "GEET Fuel Processor" made from free plans I downloaded. I used my old gokart because the carb is mucked up and doesn't run for more than a few seconds. This setup wouldn't drive the gokart because engine control is obviously tedious.
I was curious to see if it would run at all, and aim to see if it will run on watered-down gasoline, used engine oil, ketchup, soda, or any of the other crazy suggestions I've heard.
This is Test One which proves only that the bubbler can substitute for the carburetor. I still have a vaccuum leak at the block and heat issues to work out (the vinyl exhaust hose got pretty warm and soft) but it's a positive result.
