During an attempt to start the engine, and after about 5 seconds of cranking, smoke appeared above the engine cowling. The pilot turned off the fuel and fuel pump while continuing to crank. He then turned off the electrics and ran to a hangar to get a fire extinguisher. He returned to the aircraft about 20 seconds later and was able to extinguish the fire (Figure 1). The fault was traced to a sticking float inside the carburettor.
