Only way I can start it is if someone flicks the decompression once I get it spinning,the last owner broke the starting handle trip mechanism,on the sixth revolution it was supposed to trip the decompression lever.
It could also be started with an air starter motor but this last couple of years it’s given up the ghost,it needed 400psi by rights but if I connected up the road compressor and used the decompression it would start,it even had a cartridge start system but I’ve never found a cartridge to fit it.
I’m in the process of rigging up a hydraulic motor onto the starting handle,mainly because a pto turns the wrong way and a hydraulic motor would be a bit safer.
