Hello ODK Members,

This mower has appeared on ODK before, it made its way from Dalby to Brisbane where I purchased it from another collector.



The engine was locked solid and a write off, I will clean it up as an ornament though 🙂



When I purchased the chassis I was also extremely lucky to also pick up another Vinco engine which had been used as a stationary engine in a frame



The donor engine was complete but locked solid, the piston could be seen from the exhaust port and it looked very clean. I removed the head and the bore was good and rust free. A .040” oversized piston is fitted so it had been serviced at some stage of its life, exhaust port was very clean also.



I did get it free but it was very hard to turn over, I was hoping the bottom end had not filled with water over time. I decided to remove the flywheel and have a look, the magneto was fully packed with mud wasp rubbish which had locked up the engine



The Wico magneto was removed as the backing plate was broken and unserviceable, I had a spare so swapped over the electrics.



The engine turns freely and I now have spark. Looking into the bottom end I can see a very heavy crankshaft which is obviously Vinco marine inspired





I will get the engine running befor cleaning it up and transferring it to the restored chassis



🙂
