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 it. Has new gearset and revised prop shaft. Good barrels with new rings. A few parts for the magnito (fiddly) and right to go on the river again.
It was used for only a couple of years before my friend sadly passed.
I lost track of it as was sold by auction by the family.....
THEN
Out of the blue there it was on our Gumtree.....................................Got it!
Has been under my workbench for bloody years........Between projects so decided to show some love and clean it up.
Really easy but consuming doing a gentle freshen up. Everything works so basically a service as well......and paint the tank.....
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).
I then found (measured) the gap between one side of the spark plug hole to top of piston at the point of confirmed TDC. Not so fiddly as it sounds. Kept trimming down an allen key until sliding fit. I then measured the thickness.
I then did some this and that to get combined piston stop thickness required. "Insert"
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.
I will put timing tape on it (degs) to see how it stands.

Nice job I have an identical engine on my rack thats been waiting to be looked at for 10 years. Must look at it next after the OG is finished.
Apply a 7" diameter tape to flywheel. By my mark 4mm (5/32) BTDC is 32 Deg.
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 The Indian Ocean though.
I checked the timing as found. 52 Deg....WOW no wonder it ran ragged last time Mike used it. Very hard to start and sounded unhappy. Also would not run with the exhaust bypass closed. The isolated points with a multimeter (Beep setting) to confirm that. The point gap was totally out there as well.
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 centering the plate close to over the carb. That is where the points should open. So adjusting the points to just open and locking off.....ended up at exactly 0.020". No real surprise really. In doing it backwards both the backing plate is in a reasonable position and the timing is set.
So...the timing is correct, the point gap is correct and the piston BTDC is correct.
Every component is in outstanding condition so seamless and smooth adjustments really helped.
Now what next....

Finishing really early tanks is a can of worms at any time.
I had some feedback that they were blue.
I was roughly 7 or 8 years old when I first saw this motor. Many years of memory depleting substances but I think it was green.....with the remains of decals. It was rather beat up even then.
Mike made one out of aluminium .....nice job actually.
This was exported to Australia from the factory. It may have been green (sort of the green version of light blue that every motor sported from the early days).... like anzani after the black period.
Basically I am tired of blue.
To my eye a tasteful sort of green would set it off.
If anyone knows of green or can post detail pics of decals that would help make this more enjoyable.
and a great find too!
