Fortunately, the ever lovely Clive from Hartgate's in Mitcham says he can sort it - but not until Friday. Better take him some big fat doughnuts for fitting me in then. But at least tomorrow will be a clean hands day.
Good news is I fixed the leaking carb. Just a seal. But better these problems happen now than en route to Portsmouth on Saturday morning I suppose.......although that's not quite what I said at the time.
