Running an engine on homemade hydrogen

In this video we try to run a small engine on hydrogen produced by a homemade generator. It almost ran for a couple of seconds but we just couldn't get it working. we think the generator just isn't producing engough Hydrogen to keep the engine running. Also the flashback is a problem. our diy flash arrestor worked for a while but then failed in the end as well. blowing up another bubbler. music: www.bensound.com If anyone has suggestions on how to improve this, please leave a comment.
