The smoke is light blue but it's not too bad. At start up.....I get some darker smoke......I've been told that's normal. After it warms up.....smoke goes away but under load......I see a little smoke. The tractor is running great....no loss of power or hestitation. I am thinking it's not too bad right now.....someday I might need to get into the engine but....hopefully....not for a long time. I've added some diesel kleen from power services......will run that for a few tanks. Any other suggestions?

No...not really. It sounds like it is running fine and what you are seeing is pretty much par. Old rings generally mean a loss of compression that results in hard starting long before they cause oil consumption. More commonly causes of small diesels burning some oil is a gasket leaking some oil into the fuel pump or sometimes worn valve guides. Most often though it is just whatever type of fuel you are burning. I've actually had good luck with diesel injector cleaners. Apparently they aren't all created equal so if that one doesn't do what you want try a different brand.

Another maintennace trick for older Yanmars having the combo fuel gauge/fuel cap is to drain the fuel tank out, dispose of the old fuel, and sop up the water and gunk that collects on the bottom of the tank with a sponge on a stick. Those combo fuel caps leak in the rain. You can get a rebuild kit with new gaskets for the cap - or just always cover it. Or both.
enjoy! rScotty
