You're right.. I have found this video that seems relevant to converting a 4 stroke gas powered engine into a 2 stroke hho engine. The thought came to me that you need to remove the carb because hho has oxygen already in it.
Some modifications can be done to make this possible. Here is one video I have referenced related to this conversion. Alot of things I have read on this topic suggest it can be done for larger engines but with more electrical juice.
