We were in tropical rainforest with about 3 vehicles an hour passing along the road, and no NRMA, RACV or RACQ. Ian pulled the carburettor apart and found the choke float had separated. We re-attached it and screwed it up tight again and were on our way. Since then it has not missed a beat. On the flat we have lowered the fuel flow to try and wean it a bit. We are confident it will learn from this as it has its own quite human, though cantankerous, personality. Some readers might remember the days of the Armstrong system of power steering, and the Crash Craddock gearbox.
