Just got my engine back from Paul at Cleveland Models. It must have been a dodgy one, not bothered though as you can pay £200 on a picco or something and you are still going to get the odd one thats a duffer. Anyway just running this one in and it seems fine. My advice though if you are in the UK, buy one from a UK model shop rather than importing it,(I know of a couple of shops that are selling them if you can't find one, just send me a pm) it might cost you a couple of quid more bit at least if you have a problem you only have to send it by Royal Mail to middlesborough and not the other side of the world.
My opinion~ still a a great engine at a bargain price
