Need advice on Kubota injector

[twarren]

I have a Kubota T1600 diesel lawn mower. It's getting hard to start, wont rev up and is blowing blue exhaust smoke. When first started the exhaust manifold for the front cylinder is slow to get hot. Does this seem like an injector issue? Should I try to clean it and with what?

Good chance that injector is stuck and pouring in to much fuel. The blue smoke could mean rings going also. I would compression test the cylinder. I'd also pull the injectors and check them out. Should be no problem to get them rebuilt.
