considering this is from the Austrailian area it could be one of the 2 known knock-offs that were built down there.notice the different butterfly arrangement than the frisco patent.just enough design change to prevent patent infringments possibly.... see this earlier post on this site

I'm interested in the function of the pipe that connects the carburetor air inlet to the engine; also the function of what is either wires or tube that tees into the gasoline supply before the manual shut off valve.

Thanks

Barry

The cylinder water jacket only goes down half way then it is divided by a web and the rest of the jacket is an air passage. The air is then heated by the warm cylinder and drawn into the schebler carb. The two wires are for the ignitor,one is attached to the mounting posts for a ground, the other should go to the ignitor and attach to the isolated elctrode.

this is a good view of the split chamber,the top is cooling water and is salt damaged.you can see the web that splits the top from the bottom air chamber.The intake air is drawn thru the diamond set of holes in the bottom of the cylinder.

Robert thanks, I now understand the arrangement to use preheated air.

It’s fundamental that engine output is limited by the amount of oxygen than can be made available for combustion and secondly fuel must be available as vapour, not liquid. Less dense hot air does not promote increased output rather the opposite. Possibly the designers of this engine thought that by supplying hot air, vaporization would be promoted and output increased perhaps offsetting the output reduction due to less dense hot air. The complexity of the cylinder casting to preheat combustion air would suggest this trade-off.

A very spirited discussion on this subject is towards the end of this discussion link.

Another interesting observation relates to the use of a governor for a marine engine where engine load is provided by the propeller, thus a governor would not seem to be of use. The patent describes a very complex mechanism and the claims are very very design specific, nor is there any discussion in the patent abstract regarding the purpose of the device for marine use.

More mystery, however the very elegant carburetor drip container is impressive.
