Ignition timing. PART TWO: Fiddled about for ten minutes. The base plate would not centre around the top of the carby which puzzled me....no good. I have no idea and, never played with one of these before so I went backwards. Can anyone tell me the maker of this? I turned to the 32 Deg mark after c...

Now for the really fun bit....Ignition timing. PART ONE: Apply a 7" diameter tape to flywheel. By my mark 4mm (5/32) BTDC is 32 Deg. 20231211_121725 - Copy.jpg Fit to motor. Isolate points and check condensor...usual value used on everything. Being so old I will not trust it in the middle of T...

Part 2 6 mm how easy is that then. Rotated back from TDC inserted said 6mm and brought up for a firm sliding fit. Marked flywheel ignition point on flywheel. Lining up with same 4th fin. 20231211_071214.jpg 20231211_071529.jpg I will put timing tape on it (degs) to see how it stands. Ignition check...

Timing part 1 Determine TDC (piston stop rotate forward and back......take centre method). Verify TDC mark on flywheel. It lines up with 4th fin port side. It will be visible with the fuel tank attached (handy that). 20231211_064718.jpg I then found (measured) the gap between one side of the spark ...

And.....maintaining momentum. Grease gearbox. There is a detail pic of key replacement of gear pin. The pin went through the water gallery....easily blocked. Also see seal ring on new shaft. Very clever......I think something like a steam/lubricant concept? 20231210_065034.jpg 20231210_063608.jpg 2...

This was purchased by Mr Fred Goddard for the use on the Donnelly River early 1930s. He lived in Pemberton.After he passed it was taken into the care of a very young Micheal Chadwick also Pemberton. Continued use on the Donnelly until it basically wore out. Over the years Micheal slowly fefurbished...

The part to make this old dear one complete motor is the clip that holds the exhaust bypass rotor. Got one? The question is what is the correct original depth of the fuel tank and what colours were they? 20231208_074340.jpg 20231208_074406.jpg 20231208_074333.jpg Hope someone can help aye.[/color][...

Details this link. https://www.electrosil.com.au/ They were open cylinders not closed like my problem one. Very deep sc...
