Hi everyone, just wanted to say thanks for all the advice! Turns out it was the edge rockers hitting the inside of the cover. Munched some metal out of the cover and also filed down the corners of the rockers and it is fine now. Sounds good (despite the lack of vacuum advance)

One Carb Or Two?

I agree engine balancing is a good thing but I wonder how well if at all the rover coopers were balanced as I have a carb Cooper with a Janspeed head with nearly 100,000 miles on the clock that regularly hits 7k when its in use, sometimes for 2-3 minutes.
I know it will go bang eventually but it must have been a good one.
Back on topic, glad its fixed. We are learning every day :)

Crank is brand new/ old stock from rover, with regards to the carbs, I have a set of hs4's which will ultimately be going on but the hs2's will be fine for running in while I rebuild the hs4's.

Do what the old boys would have done - stick a length of hose to your ear and track the knock that way.
