Evening, made some solid progress with the engine, finally managed to loosen the rusted open exhaust valve after MANY soaks with penetrating oil and much gentle persuasion. Sadly the valve seat and valve are pitted with rust so i will have to explore a few options with that. Also we managed to get a fat blue spark out of it with a bit of cleaning up of the points. I also snapped a pic of all the dirt that fell out of the cowl when it came off just so you can get an idea of the condition of the old bus.
