Hi all,

Ive recently asked for some help after replacing carbs on my 2L CU engine. It has been tuned recently but im still not completely happy. I have changed spark plus, ignition cables and dizzy. Oil is all good. I took her for a run last night and it seemed OK. But when she got to temperature I could here a very faint knock from the engine. Its faint and consistent. Not quite sure what to do. Maybe best to take to a garage.

Anyone?

I have recorded some audio.

Here is the engine idling when cold

And the engine when warm. This is just after a run. Quite a distinct consistent knock
