UPDATE: It runs! A few days ago I hired another tilt tray truck to bring the new major back the last 220kms to our new house so I could work on it. When we went to get it off the truck into the driveway, it wouldn't budge, left wheel seemingly locked, so I used a large trolley jack to get it off the truck. However, the I had the problem of an immobile major in the driveway and a wife who wanted access to her carport.... I took the top cover off to assess the situation, and traced the issue back to the left hand brake being on just enough to inhibit movement. On the up side, the diff seemed to be in good order, no signs of water in the oil, but some condensation rust scale in the underside of the top cover. After draining the water from the tyres and reinflating, long suffering wife helped me to push it (slowly!) to the back yard. Next day I got it winding over, but no spark. Traced that back to a dead coil and sorted that issue. Happy that I now had spark, I could only get it to run by spraying aerostart down the carb while cranking it, so no fuel getting through despite me replacing the hoses and filter and the major having an electric pump fitted. After removing the bolt on the underside of the carby, a heap of silt and muck came out. That night, with the help of some 'square bear' (Aussies will know what this is)

I stripped and cleaned the carburettor and made new gaskets. This morning, it fired first go and idled perfectly (however the neighbours may not have appreciated the shot exhaust manifold

) and it undertook its maiden voyage around the back yard

even if I don't have a seat on it yet!
