cphilip! Just a quick update. Paul called me yesterday as the Kioti rep was in town so they focused some time on my 4010. They are confident the engine is at 100%. They did as test on the fuel I had in it and said it was crap. They hooked it up as is and ran it with a full load and you could hear it "spitting and sputtering". They completely drained the fuel tank, the lines, replaced fuel filter and whatever else they needed to bleed. Put 1/2 a tank of new fuel in it and it sounded perfect. Kioti rep is covering everything, even though as Paul put it, they could have put it on me due to the fuel (same fuel I've always bought so not sure what happened). They are covering the cost of the fuel, Paul's labor, new filter, etc. Couldn't be happier with the service and Kioti's response.
Side note - I had toothbar on my previous tractor but haven't bought one for this one. I ordered the one I had. Saw at Randy's a stack of them so curious if you one and if so did you get it from him? I'll eventually make it by and ask him about them but just thought I'd ask. Thanks for reading and replying! We'll have to grab a coffee or beverage of choice one day!
