My little chipper seems to be losing power whilst chipping, sharp blades ,oil good ,fuel good. It's just not producing that flat out power it has done . Seems to start to stress a bit easily.Any help appreciated,!

Which perkins engine is it? Used to do a lot of work on perkins. Fuel filters? Is it smoking?

[danroker1987]

It is smoking a little yeah ,very sparse light grey smoke you have to look quite hard to spot it .its not thick smoke. It is smoking when the engine is running full rev under no load

Grey smoke, mmm, injector? Pump timing? How many hours has it done? Do you use clean diesel from a clean can? How old is the engine?

I would start with fuel system, sounds like a 400 engine. Filters, lift pump etc.

Ok thanks for your time.Could a shitty filter be the reason for power loss,?

A blocked filter could give you those symptoms, it would restrict flow of fuel to the lift pump/injector pump. Its always a good procedure to check air filter regularly, but a blocked air filter with usually give black smoke. Any problems pm me, its easier
