You could make a nice little engine for your model boat:

Unreal.

Enjoy. I sure did.

Very, very cool.

Lots of questions:

Ignition? Did not see any plugs or wires, assume it must be sort of
a quasi diesel like a model airplane engine.

Lubrication? No sign of a pressurized lube system so assume it must
be done by hand.

It would take the patience and skill of a swiss watch maker to build
something like that. I wonder how many man hours.

It was fascinating to watch the crank shaft being turned using an off
center billet. Incredible precision involved for that and the cam
shafts.

Gene Kearns would appreciate this if he is still lurking under another
name. He'd need to downsize that 20 ft lathe of his by just a bit.


I know where Gene is, I think he has seen it by now... As to the
"ignition", it really looks to me like it is run on compressed air, no
ignition system, no carb, no plugs, no battery, no fuel rails..... One
plastic line coming in, I assume it's pressurized air

Deisel?


I dunno, the cylinders are tight but there are no compression rings. I
still don't think it's internal combustinon... No glow plugs either...

You could be right, I'm going to watch it again, but you don't need glow
plugs to fire off a fuel and air mixture. Just compression.
