Mixture of white and grey really but not black

Moisture in fuel tank, or some sort of contaminant/debris in tank?

Or head gasket.

That was the first assumption.  Apparently no problems there - no moisture and always keeping tank full to avoid this.  Not sure about debris in the tank - is it easy to tell ?

You have probably drained the tank and cleaned the filters,there might be an inline filter someone has put in somewhere stupid and its sucking air from a split in the line or its full of water.

 

Pull the fuel lines off it,put new ones on because you might have a intermitant pinch in the lines,fuel starvation or air getting in can cause the same problem you have.

 

Put a electric lift pump on it.The lift pump on Kubota's can be problematic, decent electric lift pumps are cheap.

 

Kubota is a solid brand but their starter motors and lift pumps are not the best.

All checked and ok.  It's driving me nuts - as I said one day it works perfectly and then a week later it doesn't.  Taken it to be fixed a couple of times and it worked ok when I got there 😩  It's a bloody joker

Fuel tank breather blocked?

So it chucks out white grey smoke, still runs or stops, once you stop it dose it restart up and clear it self that happen again after a while.

It continues to run but as there's obviously a problem I usually stop it and give up.  Then yes it will clear but the same thing happens again.  Sometimes it works fine for a couple of jobs but then another day I get this problem.

Think I'll follow the steps in the post from Mike Hill in the hope that it can be fixed.  Failing that I'll probably just get another one
