Hi Niall, Just a thought but did you by any chance have to remove a vacuum pipe when fitting the new carbs. This reminds me of what happened on my H4 and also on my Beauford when one removed the crank case closed circuit breather connection to the manifold.
Any odd tapping points around the manifold that look as if they should be attached to something? Try putting your finger on them to see if the problem goes away. If yes, then look for the missing hose! Good luck!

But yes runs like a dream under load it's just on idle (or not being on idle!) that's the prob. Made some progress this morning though, bought some carb cleaner and started playing around - looks like there is a vacuum leak. It's either somewhere around the base plate under where the throttle mechanism goes into the body - or in the throttle mechanism itself. Can't be sure and now the car is overheating so I'll go back out in an hour and have another play!
