Oh well I've got to the bottom of my no fuel problem. I got a compression gauge and found no compression so off came the head and barrel and what should I find. Both piston rings seized tight into piston and quite bad scouring on piston and in the barrel. It would seem that it failed on the run or had been failing for somtime before but due to the heat of the engine and oil sealing it there was enough suction to get fuel to the chamber. Once cold and unlubed the compression / suction was not enough to suck fuel in. Oh Hum looks like I'll be looking at a bigger bill to get it back running again. At least the fault has been found and I now know what to do to repair it. taz.
