The following came from Brian by email. I'm not sure who he is refering to about the "one restored on a trolley...".
Hi At the Hervey Bay Historical Village & Museum we are about to begin restoration of a Chapman Super Pup. Any thoughts you can give related to this project would be most welcome. How was the engine cranked to start it? There does not appear to be any provision for rope pull or crank handle. When you restored the one you have on a trolley, how did you set up the cooling water circulation? We have a picture of ours on the web at: http://herveybaymuseum.museum.com/chapman.htm
Most Blaxland engines were strap started or rope started from a small notch with a pin on the front of the flywheel. Others such as the master pup had an additional smaller wheel on the drive end of the engine. From what I've been told (my engine is still under restoration) they can be started by just rocking the flywheel or the application of a firm boot to the flywheel to overcome compression. I hope this helps.
