I'm quite pleased with myself today. We have a 1911 Sunshine tractor ( Very rare! only one other in existance as far as I know) in the shop and I havebeen working on it for a few weeks now. It had a crack in the engine water jacket and the carburettor flooded all over the place. The float was made of cork and was completely stuffed. I made a new one from a large thermos flask top and sealled it with epoxy, then made a new needle and seat. I finished that last week and then started on the crack repair. Put a magnaflux on it and found that the crack was about 125 mm long. I drilled the ends of it then cut it open with a small disk in a Dremel ( actually a lot of disks, they are pretty fragile) then bogged it up with a Epoxy steel putty. I had to remove the water pump to get at the crack . It drives the magnito as well. Despite my marking everything, somewhere the timing got lost. I spent this morning figureing out where it all should go. It started on the second crank! We ran it for a bout half an hour without leaks or flooding. The next task is to get the second carburettor sorted out so it can run on kereosene as well. I can't find a throttle on the carbby so there must be something I'm missing. Anybody know anything about early kero carburettors?
