After watching the video of Jin running the prototype Holt copy engine it’s obvious that he has it running backwards. The original Holt engine when viewed from the back Flywheel side with the pushrodrods to the right, the flywheel rotates counter clockwise. Jin’s engine rotates clockwise from the flywheel side and with the push rods to the right. The fix would be to machine a reverse ground camshaft then the engine could be corrected which would make the water pump and fan turn in the proper direction. If you look at Jin's video closely the O-ring belts are not flipped over.
