today i got my 4 stroke 150cc lawnmower running off pure 100% hho. although it was only 10 seconds at a time, it gave me a pretty good idea of how much hho is needed to run an engine. obviously my cell doesnt put out nearly enough to keep it running or even start it. i hooked up a balloon to a tee fitting to store about a minutes worth of hho with and hooked up a valve mid way to the lawnmower. i removed the air cleaner and hooked up/sealed a hose going into the carb where the air cleaner used to be (i also used a home made spark arrester and bubbler for safety). i obviously drained all the gas from the tank and gave it 10 or so pulls to make sure all the gas was out of the system and blew everything dry with compressed air. basicaly a 6" balloon worth of hho runs my 150cc lawn mower for 10 seconds before it sucks everything dry. i feel pretty motivated to build a bigger/better cell now and a better way of storeing small ammounts of hho
