    Nice build. I am wanting to start one of my own. How did you go about making the ignition system. I have the plans from modelengine maker forum, but I didn't see anything on the ignition system.

      There is a build thread on the Model Engine Maker forum. In there are the drawings for the engine.

    True Craftsman, Lovely work, thank you for showing us.
    I would enjoy an explanation of how the hit or miss flywheel works ?
    Kind regards

      +Malcolm Till
      There are two weights mounted on a hinge joint on the flywheel. As the flywheel spins centrifugal force throws them outward. Attached to the weights are arms that reach inside the flywheel. The tips of the arms locate into a spool which slides along the crankshaft. The spool has two slots, one for the arms and one for the lockout lever. The lockout lever engages the exhaust pushrod when the engine picks up speed, otherwise it stays clear of the pushrod to allow the exhaust valve to open and close. When the exhaust valve is held open there is no vacuum in the cylinder when the piston goes down the bore so if there's not vacuum the intake valve wont' open so no fuel charge is drawn in. On full sized hit and miss engines when the pushrod is locked out it also prevents the ignition from firing.

    Why don't they reduce the sound produced by the engine? I'm surprised that an engine this big and produces such a loud sound!

  • @alanm.17

    I see only 1 valve controlling what appears to be the intake, how is the exhaust valve managed. Or is this a two stroke engine.

    • @seeburgm100a
      @seeburgm100a 7 років тому

      Look closely there are two valves.. the intake pulls in by itself. The exhaust is controlled by the pushrod etc.

    • @ronfullerton3162
      @ronfullerton3162 4 роки тому

      The exhaust valve remains open until the governor calls for power. Up until then, the exhaust valve is held open and air is going in and out with the piston movement. When the governor calls for power, and the exhaust valve is closed. The intake valve is a "poppet" valve, which has enough "spring" tention to remain closed until there is a vacuum. The exhaust valve closing on an intake stroke creates a vacuum, and the intake valve opens allowing a fuel/air mixture to be sucked in, followed by comprehension and power strokes. If the power stroke speeds up the engine enough to open up the governor, the engine will begin freewheeling again.

    Will it run slower?

      I'll have to experiment with the springs on the governor weights. Being that it will start by hand I'm sure it will run slower. How much I don't know because of the small size of the flywheels.
