Knowing the bike to have stood for at least three years with a half tank of av-gas it seemed prudent to whip the carb off and subject it to a thorough de-lousing. The air box is a bugger to get out but I'm very glad we persevered - it is in a shocking state, the filter is long gone, leaving a residue of decomposed crumbly element foam stuck all over the inlet tract. The carb is actually seized solid inside with fuel goo. I don't know whether av-gas deteriorates in a different way to regular un-leaded but I've never seen anything as bad as this before - the dark molasses coloured residue has the consistency of chewing gum and is equally reluctant to let go. The Diplo chemical cupboard has been opened and we've tried cellulose thinners, meths, paraffin, de-greaser, acetone and many more products which will have to remain unidentified. We've made a start on the tank - not so much a rust issue as a goo problem, well goo and rust combo.Let you know how we get on. MORE ETHER !
