Hello guys

I'm planning on making a 150 cc petrol engine run on only HHO has the will power a 200kg go-kart. Through a dry cell battery with a car battery attached to the go-kart, plus the alternator to recharge the battery.

What I'm asking to start off with is...

1. Is it even possible to run a petrol engine of that standard on HHO

2. Will I be able to recharge the battery as well as produce HHO to run the engine

3. The specs would be around

30MPG
Max 4000rpm
150cc ish
I will make the required amount of HHO in LPM if it's possible as feasible

Anything else you tell me that you think would be useful?

Thank you I'm new to this HHO business
