Congratulations!

Looks to be a nice one and certainly hope it runs as good as it looks!!!

Finely got it in. Haven't tried to run it yet.

I ran mine on acetylene with no problem. Doubt it would harm it unless you plan on running it long term. I have a youtube video of it on "town gas" as well at Coolspring awhile back.

Yes, Carl's special hydrogen cigarette lighter.

Sadly those cigarettes put him in an early grave.

About a month before he passed I got a call from him to share the sad news.
By the time he was diagnosed it was way too late to do anything about it.

He was one of the good guys.
R.I.P.  Carl

This guy went to the trouble of having the gas mixed.  And he has a unique use for the engine.

Does anyone here have a Paradox engine that you run, and what are you using for fuel? I seen where people have had mix of different gas made for them. Was just wondering if there is a gas that will work with out having it mixed.

Talk to Wayne Grenning. He knows exactly what it takes to make these engines run. Unfortunately, it’s not really financially reasonable to have the gas mixed for the small amount needed for these engines, but you can have the separate gasses mixed in a manifold before being fed to the engine, but it would be quite an elaborate setup. I was going to try to make mine run this way, but it just doesn’t seem worth it to me with all the expense and fooling around.

Is that a flame-eater sort of engine in the video?
A pretty vigorous runner, I think.  Another 'Would
like to have' item.  They pop up frequently

Wayne

It is a non-compressing flame ignition valveless gas engine.

That sounds to me like maybe acetylene gas for fuel.

These engines will run on acetylene, but it is too explosive and is very hard on the engine.

This......

They were run on illuminating gas which was also called street gas.

What is a Paradox engine ?

Paradox is a good name for those engines. I think they came from a parallel universe, like up is down.

Hydrogen should work without mixing.
