Is that a C30 model and do you know what year? Attached is a parts list and operating manual with wiring diagram, air diagram etc here for C30 to C50 models from 2003-2009 year machines. Might help you for fault tracing etc.I have a 2 cylinder deutz engine on a compair road compressor. It will fire up but wont run. Every time I try and start it, it will always fire up for a second, but something is preventing it from running. Anyone any ideas?
