Cheers Chris
Have seen these but most have a 19mm and 25mm suction cup which is too big

You can use fuel line on the stems to spin teh valves. (do it from the top side). Don't need the suction cup dealio-which in my experience aren't all that hot anyway.

Old school all the way! People were figuring this stuff out long before I came along and knew it all...
