Hello All
First time post.
I have a Cub Cadet UTV (aka Massey Ferguson MF20MD) with a Perkins 403C engine and CV transmission.
The engine is also known as a Cat c0.7. I know that the engine is used in many other vehicles and plant so I'm hoping that someone here may have some thoughts on my problem.
The UTV starts and runs fine, but gives out gray/black smoke constantly. More smoke under load, less at idle, but all the time. The engine is otherwise good. Compression OK, injectors cleaned, new filters, no excessive oil or water consumption.
I think the engine is over fueling. I also think that previous owners may have adjusted something to try and fix a bad starting problem that I fixed with non-return valves in the fuel hoses.
Is there a safe adjustment that affects the fueling over the whole load range of the engine?
The other thing that happens is that the engine loses power when pulling away after idling for a few minutes, then it recovers and pulls normally again.
Best regards..............Jonathan
