Thanks for the heads up tookey, I am going to look in to that option. A quick update as to what I have been up to... I haven't found the source of my puddle of fuel probably because the bus has been starting right on the button ever since but having just seen tookeys findings I shall change the manifold boots because they do appear to be of a certain age and it certainly wont do any harm. I have replaced the pancake filter with a standard paper element air box and the 009 dizzy with a SVDA jobbie and the difference is fantastic. I have only been on a short run but the flat spot is gone and it feels like there is a tad more grunt which enables the old girl to get from 0-40 in a reasonable time ( I have now binned the sun dial and am using an egg timer to measure this). All in all everything is moving in the right direction, just an original 34/3 to find so I can replace the 30/31 that is on at the moment.
