Does anyone know where parts can be obtained for Ruston Hornsby engines? I am repairing an injector for a 1HR engine and require a new nozzle. Also can anyone tell me how many spray holes the injector for a 1HR has. The injector I have is very badly corroded and I cannot tell if it had 1 hole, or 3 holes as the larger engines have. I have a selection of used nozzles for larger models but nothing to sit a 1HR.
