After a while I have eventually got going (knacked!) and not then had a problem once warmed up, so I don't think there is any real issue with the engine as it CAN run ok...
my guess is that tilting the engine is causing fuel to syphon back into the tank, leaving just a small amount in the carbs for it to run briefly, but causing an air pocket in the pump - which only works with fuel in it!
next time, once youve lowered your engine into the water re prime it until the builb is rock hard. i am certain this is what is causing my problems as repriming seems to sort it for me.
