Hey folks I have a S220 with the kubota and it smokes when cold. It cleares up alot when hot though. It has plenty of power and uses no oil. The oil does not smell like fuel, but the exhaust does. I think injectors, it has 2600 hrs on her now. And if it is injectors, how hard is the process to get them out, and who rebuilds them in the Kansas City area. Thank you
