Hi Guys,
I just stumbled across this site and cannot believe I have not seen it before!
I have a question I hope to get some advice on:
Occasionally when starting the (diesel)Kubota, It will start and rev extremely high right away and shut itself off. It will then have to sit for 5-10 mins and then will usually start right up

Look forward to being a part of these boards!!

Thanks
Chad

So far my research suggests maybe fuel filter, bad nozzles or fuel pump

So I replaced the fuel filter on the weekend and I went out to start it up this morning, the following happened:
1. Glow the plugs for 25 seconds
2. Started it up
3. Began revving higher and higher
4. Tons of dark grey smoke was coming out of the exhaust
5. I turned the key to the off position
6. The engine kept running hard even with the key off
7. eventually after 20-30 seconds it began to rev down and shut it self off

This only happens when starting the machine cold, It does have a block heater and if plugged it starts fine. Last winter though the machine never did this. I am worried this will lead to a future (larger) problem(s).

I am not sure what the heck is going on here and if anyone has had previous experience with something like this I would love to hear from them.

How many hours on your machine.

When people mix gas into diesel engines they sometimes rev uncontrollably.

The smoke would indicate a possible head gasket leak.

Just some thoughts.

I would drain all the fuel out of the tank and replace with fresh fuel that you are sure is clean and fresh diesel.
