Hey Kubota guys. Motor was running fine then idle slowed to a stop. I noticed there was no spring tension on the throttle lever. As I suspected the governor spring came off and luckily ended up under the injector cam. I put it back on, put it all back together and as soon as it fired up it immediate went full throttle! Had to block the turbo inlet to shut it down. It only ran for less than 5 seconds like that but filled my shop with heavy black smoke. Any ideas?
