On Zip File 4 (Parts List) of above link (pages 27a and 29b) you will find the diagram of the governor system. Check the external springs for throttle return are all on your engine and working. Could be a problem with the internal governor as shown on the diagram.

Re: Yanmar YSE 8 fuel injection issue?

Hey it has been a while since I posted anything on here.
Anybody still following the thread, the mechanic who recently rebuilt my engine didn't tell me explain the details, just that it was submerged partially and he kicked it back to running. It ran great for a year or so with the exception of the black sooty water out the cooling system. I replaced some of the pipes and this seemed to help a bit. It doesn't seem there is a cracked head gasket as of now because I run it extensively without any explosion. It has spit diesel and oil out from somewhere and its oil leaks do seem to be increasing. I have a few folks take a look at it and nobody has been able to diagnose the issue but could be there is an internal linkage regulator issue.
I'm taking it to a pro tomorrow so we'll see how it goes...
