I just got my first Kubota ( used ) I think its an 82 and the model# is B7001 I notice that every time I start it white smoke come out the muffler and also when I shift gears what would that mean..?? would a maintenance check and tune up help..?? thanks in advance johnny
 
Diesel? White smoke is unburned fuel. Probably a bad injector but it could be poor compression.
 
Do you know how I can check the compression is it checked like a regular gas engine which I know how to do but I know nothing about disel engines ?? Thanks in advance Johnny
 
Not that easy on a diesel. They have extremely high compression and I don't think a typical compression test gauge goes high enough. It's possible to find a dead cylinder by using an infrared thermometer on the exhaust manifold when you first start the engine. Live cylinders will heat up very quickly.
