Dumper - no power

[Greengrass1]

Morning all, I was wondering if you experienced mechanics could help me and guide me in the right direction. The petter engine on my dumper is running but lacks any power. Please could you offer me advice? Many thanks.

Hi Alex, well start by checking the easy things first which is; a good clean fuel supply, a clean air filter and that any flexi-intake pipe/hose is not collapsing internally, also check that the brakes are not binding on, perhaps you could give us some more details.

To add to Jeremy's post: if you try turning on the handle without the decompressor, is it difficult or easy to pull through the compression stroke?

Morning all, I will do some more investigation and report back.
Many thanks.

Evening all,
After some investigation, it is the clutch slipping! It is a brake drum / chain drive set up so going to adjust and hope this works!
If not I will be researching how to change the clutch.
Thanks to everyone who helped.

Alex, glad you have found the problem, hopefully that should have been the most difficult part of the process.
